The guide reports verified programme or complaint processes. It does not promise an outcome or turn a complaint into a finding.
First classify the dispute
A disputed charge is not by itself proof that a casino, merchant or payment provider committed fraud. Record the amount, statement date, merchant descriptor, what you authorized and what was promised. Distinguish an unrecognized transaction from an authorized payment where the amount, billing or service is disputed.
Contact the merchant when the transaction was authorized
OBSI says cardholder agreements and legal rules generally require consumers to approach the merchant first. Explain the problem, the outcome requested and a reasonable response date. Keep the original receipt or terms and the complete correspondence. If the charge was not authorized, contact the card issuer immediately rather than delaying for a merchant exchange.
Ask the card issuer about refund or chargeback
If the merchant does not resolve an eligible problem, ask the issuer what dispute or chargeback process applies. OBSI says consumers normally must cooperate with the bank's investigation and provide relevant information truthfully and promptly. A provisional credit may later be reversed if the request is not upheld.
Do not miss the deadline
OBSI's guidance says consumers generally must dispute a charge within 30 to 45 days from the statement date, while agreements and network procedures set their own strict timelines. Check your own agreement immediately; this page cannot extend its deadline.
What OBSI reviews
OBSI reviews eligible disputes between a consumer and a participating financial institution. It says it does not directly investigate or recommend compensation from the card network or merchant. Its focus includes whether the bank followed rules and policy, treated the consumer fairly and made a reasonable evidence-based decision.
Escalating a bank complaint
Federal guidance says a bank must provide a detailed written response within 56 calendar days after the complaint begins. A consumer may contact OBSI when the bank closes the file with a detailed response or when more than 56 days have passed, subject to OBSI's terms. Provincial credit-union processes may differ.

Quick answers
Does a disputed casino charge prove fraud?
No. It identifies a transaction that needs evidence and review; it is not by itself a finding against a merchant or payment provider.
Does OBSI decide the dispute with the casino?
No. OBSI says it reviews eligible consumer complaints against participating financial institutions, not the underlying consumer-versus-merchant dispute.
When can a bank complaint go to OBSI?
Federal guidance says generally after the bank closes the file with a detailed response or after more than 56 calendar days, subject to OBSI's terms.
