This is the cost of avoiding the ToS and not reading it at all. They have the right to freeze your account the moment you violate the ToS.
If you can provide KYC and didn't violate any rules and regulations, then it is still possible to recover but in your case I doubt on this.
The site will never inform you if they are going to freeze your account to avoid immediate withdrawal. So learn from this lesson and never violate their ToS. Using VPN is quiet risky as well.
Sometime ago stake froze my account which had about 100 thousand dollars when I reached out to them I was told o had exceeded my bet limit I was able to place bets but not withdraw my assets I reached to a US company at adminctrackltd(at) protonmail(dot) com that specializes in crypto assets recovery,they recoverd my frozen funds on stake.
I'm just wondering why many are attacking Stake nowadays? Any proof on this?
