Before you act on anything here, confirm the facts of your own case. Check the bet slip or transaction history in your account, note whether the funds left your bank before the operator's record shows the deposit, and be clear on whether the issue is a stuck deposit, a reversed naira transfer, or a wager settled against your reading of the market. A dispute about an NPFL match abandoned partway, or an EPL fixture decided by a VAR call, turns on the operator's published rules rather than on what felt fair at the time. Keep screenshots, USSD confirmations and bank statements, and note the time each step happened.
The two guides here work in sequence. One deals with raising the complaint and getting a response, the other with escalation when that response falls short. Read them together before you contact anyone, so your first message already carries the details that make a resolution quicker.
