I recently won a decent amount betting on Bet365, but the bookmaker didn’t want to pay out, accusing me of fraud. I somehow proved that everything was legitimate, but the whole situation really shook me, and I don’t want to place bets there anymore. In your opinion, which bookmaker would be better to switch to, one where problems like this don’t happen?

Can't say for sure, my friend uses that same bookie and never complained about anything. Large payouts always get scrutinized by betting sites though. They're not exactly thrilled about handing over massive sums. But once they verify your account is legit, they'll process the withdrawal. I'd hold off on jumping ship to another bookmaker just yet, though ultimately it's up to you. Maybe check out 1XBet as an alternative. Their odds are basically the same. Or browse through multiple options here https://betclone.com/. After that you can figure out which platform suits you better.
