Product: Checking or savings account

Ok, on XX/XX/year> a family member ( XXXX XXXX ) sent me {$1000.00} to help me pay my bills and take care of my children until I can get back on my feet. I received the money into my XXXX checking account that night. I put in to transfer it to my chime account and went to bed. I woke up the next morning to find my transfer was canceled and saw multiple unauthorized transactions made from my XXXX checking account. I called XXXX and told them about the unauthorized transaction and told them I wanted to dispute the transactions. They told me that I had to wait until the transactions posted to my account before I could start a dispute. XXXX days went by and they posted to my XXXX  Checking account. I called XXXX back to dispute the transactions and I was told that the account has been restricted and is under investigation! I asked why and they refused to tell me! I asked if they needed information and they refused to say anything but XXXX sorry but the account is under review and we can not give you any information at this time! So we hang up and I called back every single day asking for information about my account and again they say XXXX sorry but the account is under review and we can not provide any information at this time! So everyday I called XXXX XXXX times a day until XXXX weeks have passed and XXXX still calling and I get the same answer XXXX sorry but the account is under review and we can not provide any information at this time! every single time I call! They started hanging up on me when I called because I was as furious with them! That happened multiple times! They are rude! They were only supposed to dispute the unauthorized transactions, not put it under investigation ( I have done nothing wrong ) and refuses to give me any information about my XXXX checking account! I have demanded to speak to a XXXX or supervisor every time I call and they say im sorry there are no available managers or supervisors at this time also they say Please call back at a different tine to speak to XXXX! They would not give me a specific time to call! They tell me this every time I called back! They also asked me for a good call back number, I gave them my phone number and to this day Wednesday XX/XX/year> I have not received any calls from them! I have also emailed them and still no response and my account is still under review and no updates have been sent to me! They never have anyone above their seniority available to speak to! I have asked them repeatedly to take the restriction off the account and let me remove the remaining balance to another account so I can pay my bills and provide for my children and they tell me that they are not authorized to remove the restrictions! So I asked to speak to someone who can and they say im sorry there is no direct line or number to contact them! They are holding my money that is in the account and refuses to let me have it! They started an investigation on my account without my knowledge until I realized it had the restrictions in place!! I did not authorize them to do so! I have not done anything wrong for them to restrict my account! They were only supposed to dispute the unauthorized transactions and get me a new debit card, but no they restrict my account and give me no access to anything and they refuse to give me any information or documentation that I have asked from them! I want to get the money that is in my account and close this account with XXXX!! I need that money to take care of my necessities and they REFUSE to help me at all! I am very very very furious with this company!! Something needs to be done!! I will probably contact my lawyer! Please help me in this situation?!
