I think you should add some more context on your activity on their site : some sort of chronological history of your betting activity after the deposit, if you were doing sportsbets, eventually what kind of ( I mean main events or secondary sports that sometimes are involved in fixed matches), rather than playing casino games or both; if you claimed welcome bonus or other kind of bonus/promotions ( that in my experience are the main reason of accounts being blocked/limited) or if you deposited and played straight away; if your bankroll growth was due to a big win or if it was a steady one...
Just to allow us to have a wider picture of the whole situation.
I made a deposit, and in around a week made sportsbets/casino gambling. When i reached a good balance (within a week) i requested my first and only withdrawal.
My bets were essentially made in esports, no matchfix at least to my knowledge, and if I remember correctly it was a casual balance grind, no "big" win.
Just wondering, why have you waited 7 months before creating this thread? Up to 3 months is more than enough time for investigation or security check. They have taken too much time already. As 'Zwei' has said above, you may not see any positive outcome here. Moreover, they won't refund your deposit. And you won’t get any proper explanation from them. Their reputation is too bad in the mediators as they always fail to provide evidences to justify their decision. You will find most of the complaints as unresolved against Betpanda in the mediators.
I believe they didn't have this kind of presence on the forum when I had a problem with them. I was also waiting for the results of the verifcation but as i said before, no answer.
