The appropriate contact depends on where you live, where the provider operates, what happened and how payment was made. A language version of this site does not determine jurisdiction. Start by identifying the issue: suspected criminal deception, a regulated-service complaint, a consumer dispute or a payment problem.
Police or an official cybercrime reporting channel may be relevant to suspected crime. A financial regulator may publish warnings and authorisation registers, but may not resolve an individual payment dispute. Consumer-protection bodies may provide information about consumer rights; an ombudsman or dispute body may have specific eligibility rules.
Your bank, card issuer, payment provider or exchange can explain its own reporting options. Contact it through its established app, a trusted statement or a website you independently verify. Explain the dates and payment method without assuming that any particular refund procedure applies.
Check each organisation’s remit, country coverage, eligibility, deadlines and official submission route. Reporting a concern does not guarantee investigation or repayment. RECOVANT may explain these categories, but does not select a legal procedure for you, act as your representative or submit reports on your behalf.
