Ironically, while I've had some strange KYC requests over the past few years, Bookmaker is the only Book to freeze my account and hold money hostage for over 3 months. I got the run-around forever and it wasn't until I said I would start bringing this up on the forums until any movement was made and they finally unlocked my account. I think it was an anomaly but proof that we are only a bad circumstance away from something like that anywhere, even with the domestic US books that are licensed, to be honest.
I'm pretty sure I know what led to them unlocking it because of timing but it was brutally bad communication on their part. I had a BM account and then months later, opened a JustBet account. Thing is, I got on to support and asked them if this was an issue because I couldn't afford to lose my BM account and before I deposited one cent, they said it's perfectly fine. 3 Days later both accounts were locked and then the nightmare began with weekly checks and weekly excuses.
