Managing an account: Checking or savings account

My Bank of America account has been restricted for almost three weeks after my car finance company attempted to process a payment Since then I have not been able to withdraw my money, transfer money or access my own funds I have contacted the bank multiple times and have not received a clear explanation or a resolution The issue remains unresolved and I have been left without access to my money for weeks This has caused me serious financial hardship because I have bills due at the end of the month including my rent, and I can not pay them since Bank of America is holding my funds I understand that banks need to investigate suspicious activity but keeping my account restricted for this long without resolving the issue or providing clear communication is unacceptable I am asking Bank of America to immediately review my case, remove the restriction if there is no valid reason for it to remain, and restore my access to my account
