Make the problem specific
A rejection letter is upsetting, but a useful complaint identifies the decision you want reviewed. Ask which agreement or certificate clause the provider relied on, which facts it used and what evidence would change its decision. State the remedy you seek: for example, correction of a disputed charge or reconsideration of a claim for a specified amount.
Use the provider’s official Complaints Unit. BNM distinguishes this from the Business Unit or Claims Unit; sending a claim is not the same as lodging a complaint. Keep the date, acknowledgement, reference number and copies. Ask for a written final decision. An initial claim rejection is not automatically the final decision on your complaint. A phone call can help clarify things, but follow it with a dated written summary.
For an unauthorised transaction, contact the provider promptly to report it and protect the account; do not wait for an ombudsman deadline before taking that first step. A complaint also does not itself cancel a debt, extend certificate cover or suspend a payment obligation. Ask about any disputed payments in writing.

Choose the route by what you need
FMOS combines the former OFS and SIDREC services from 1 January 2025. Its current membership and rules are the starting point for new disputes. A complaint about regulated conduct and a request for individual monetary redress can involve different functions.

Who and what may qualify?
FMOS covers specified member services: banking, Islamic banking, digital banking and payment instruments; insurance/takaful claims such as medical, motor and travel; and capital-market products and services. Check the exact legal entity in its member directory.
Eligible groups include users for personal, domestic or household purposes; micro and small businesses under the applicable definition; individual investors or sole proprietors in member capital-market dealings; and specified guarantors, beneficiaries and group-covered persons. The conditions for each group differ. The examined eligibility rules do not distinguish Muslim from non-Muslim complainants. Foreigners may also qualify for member services. FMOS makes the eligibility determination.
The normal limit is direct financial loss of up to RM250,000 per dispute. Beyond it, a joint written referral agreement is required rather than unilateral access. Do not divide one dispute into smaller claims to assume eligibility; FMOS determines whether it constitutes one claim or more.

Important exclusions
A wish for a cheaper price, a loan approval or a restructuring concession is normally a commercial decision outside scope. Poor investment performance alone is also excluded. Alleged non-disclosure, misrepresentation or mis-selling may fall within the stated exceptions; explain the conduct and loss rather than simply asking FMOS to change the price.
Other exclusions include cases filed in court or referred to arbitration, third-party bodily injury/death claims, certain actuarial methods, and disputes over payments made under Schedule 10 of the relevant financial-services laws. There are also exclusions concerning insolvent members, time-barred cases and certain authority-directed investigations. A nominee or beneficiary can be an eligible complainant under Rule 3 without every nomination/payment dispute falling within scope under Rule 5. Read the full exclusions or ask FMOS; this list is not exhaustive.
Build an evidence pack, not a pile of screenshots
Keep a short chronology and link each document to the point it proves. For a rejected medical claim, the certificate and schedule identify the cover; the clinical documents and bills identify the event and loss; the decision identifies why it was rejected. A brochure or cashless card is not the full certificate. PDS means Product Disclosure Sheet. Use the official FMOS checklist and forms for your type of dispute, including any required identification and permitted-disclosure form.

Record both issue and receipt dates
The original Rules normally require referral within six months of receipt of the member’s final decision. Rule 6.2(c) qualifies this when the final decision omits the filing-deadline notice: the clock starts with a later written notice that supplies it; if no communication ever supplies it, that rule sets no filing deadline. Other statutory limitation exclusions remain separate. Rule 6.3 also gives FMOS discretion in specified late-referral circumstances. Do not rely on an exception or calculate your own extension: contact FMOS promptly with the actual letters and dates.
If the member fails to respond within 60 days after the first complaint, the no-response route may be used. If you have only an acknowledgement or an ambiguous reply, ask FMOS how the rule applies; this article does not decide that it counts as no response.

What happens after referral?
FMOS screens jurisdiction before registering a dispute. Case management seeks a settlement; adjudication by an Ombudsman may follow if the dispute is not settled. Read every notice: the Rules provide 30 days from the date of notice of the Recommendation to request adjudication, and 30 days from the date of notice of the Adjudication Decision to accept or reject that decision. If you accept the decision, it binds both you and the member in the manner provided by the Rules. If you reject it, the FMOS process ends and other avenues may remain. Do not assume an appeal within FMOS.
The service is free to complainants and a lawyer is not required for the FMOS process. Gathering documents or choosing separate legal advice can still have costs. FMOS describes a usual resolution target of three to six months from complete documents, which can be extended for complexity; it is not a guaranteed payment date.
BNM’s current complaint page requires the provider’s Complaints Unit first and allows a BNMLINK referral after 14 days without a response. That is a separate BNM complaint step, not the FMOS 60-day no-response rule. BNM lists cases already referred to FMOS, courts or tribunals outside its complaint scope, and does not give legal interpretations of contracts. Check that scope before choosing a route.
For regulatory concerns use BNM’s complaint page or SC’s complaint page. SC explains that it reviews possible securities-law violations and cannot be your legal adviser or resolve private civil disputes. The SC page still names SIDREC in one redress paragraph; use the current FMOS originals linked here for the new scheme. A regulatory complaint is not an automatic compensation award or deadline extension.

Before you send the dispute
- Identify the exact member and your relationship to the product.
- Write a one-page chronology and the remedy/amount sought, with its calculation.
- Attach the applicable contract, event evidence, complaint and final decision or first-complaint record.
- Record the receipt date and deadline notice; ask FMOS promptly if timing is uncertain.
- Check the exclusions and disclose any existing court/arbitration proceedings.
- Use the official filing instructions and FMOS portal; keep your submission and reference. Follow later response deadlines.
Research context, not today’s filing rules
Hakimah Yaacob’s historical work on Islamic-finance dispute resolution is relevant background. UUM’s publisher record credits her article Party autonomy over jurisdiction clause in Islamic Finance, published 25 December 2011. Its subject helps explain why forum and contract questions deserve attention. It predates FMOS; this guide does not treat that research as current complaint rules or claim to reproduce its findings.
