Sounds like you had the standard 1xbit treatment.
If your account was in profit they just block it and ignore you. This has been going on since the dawn of time, yet people keep falling for it.
I was aware that my account could be blocked, I've read that topic before. But I've also read that deposit is always returned.
There are many bookmakers in my country but to be honest no one can be compared to 1xbit in terms of matches offer.
Unfortunately, if you would like us to take your complaint seriously, you should provide some evidence that you have actually made any deposits and placed your bets on sport events. Without this, no one will recognize your complaint as genuine.
