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)
I don't know if anyone else has pointed this out to you first, but just incase no one did, then take this as a point of correction that, casinos don't ban players when they have a nice winning streak, atleast, not well known casinos like stake with some level of good reputation, that would be such an unfair thing to do.
What I know is that, casinos limit players who seem to be winning too much, they sometimes either limit the player in the area of amount of money the player can bet on a game, or limit the player in the area of games the player can bet on, but it's also good to know that when worst comes to worst, the casino might limit the player in both ways, but this is very rare, they may either limit the amount of money you can bet, or limit the games you can play.
In your case, your husband was first limited on his account, which is a normal thing for an account that is wining too much, then he opened a second account with your name, and this time, after winning, account was banned, now, it's no longer an issue of winning too much, but an issue of multi - accounting, which is a well known crime in most casinos.
Like you have decided, provide all that they are asking in terms of account verification, and I trust that when you and your husband manages to convince stake that the account belongs to you while the other belongs to your husband, then they should possibly lift the ban and allow you to withdraw your money.
