Quoting your post to make images visible for a better reading.

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.
