Yea and it happens when i win 5 bets in a row and not when i'm making deposits over deposits...i told them i was available to share my monitor and show them whatever they wanted..dont know about your experience or why you claim such things on such a important topic without any proof but this is not the case.
Sorry to say that you are not the only person who is facing this kinda situation after winning big. We have seen many cases like this in the past where in some player use VPN or multiple account to place their bet. Even sometime platform lock withdrawal due to using same IP although it can't be a proper way of freezing players fund.
Have you contacted them through their forum account?
