Will not release my $ to me.

I’ve used Gemini for several years. Suddenly I started having issues with signing in. Password did work and passkey didn’t work. After a month of back and forth with the AI response system. I finally got it ironed out. Very frustrating. Seemed shady. So I cashed out all my coin. Went to withdraw to bank account and now have some restriction that makes no sense. Cannot get a straight answer or resolution. It is going on a month now and keep getting blown off. Cannot get ahold of a person to remedy situation. It’s not even a large amount money. But it’s my money. I cannot use it to invest in anything else and they are collecting interest off my money they are holding ransom. If this company is doing this to many of their customers the income to them would be substantial. This seems highly illegal. Could someone please give me some advice on how to remedy this so I can get my money and close the account and delete this shady app asap.
