Green Dot Bank complaint: Froze and cancelled my card with my tax return balance 5700$ out of 10600$ still on it; said i was not account holder n flagged fraud….

I have used my card previously with my same information i.e. address, phone number, emails, etc. I called them ahead of time approximately 4 different times, making sure my tax return could be automatically deposited after they reviewed my return for 120 extra days. After my deposit of 10600K was made, i spent and facebook paid, and a transfer and withdrawal over a few days time, they froze my account and said that i was not the card holder. I still have another 5700$ and they say that i have to give exact instructions to the financial office who transferred the money to Greendot that would request the balance from them and ultimately be sent to me via check in the mail by that financial institution. It was an ACH direct deposit (Automated Clearing House Direct Deposit). WHAT DO I DO? Why can’t they send the check themselves to my home if they’re the ones having identitiy issues with all their customers??? I believe they just want to sit on our money.
