Thank you for your reply. It's my first time posting here.

Indeed what we did seems to be against TOS but we weren’t aware of it. As I said, I didn’t even know casinos would ban players if they had a winning streak.

Stake is holding my whole balance for now. I will comply with what they are asking and send all the documents they need.
I am just asking for the money to be sent, not the limit to be raised again (although ultimately i would like to be able to keep on playing)
