Problem with customer service: Money transfer, virtual currency, or money service

Bank of America branch staff refused to verify a $42000.00 personal injury settlement check at the counter and forced me to use the ATM. The bank partially released funds, then clawed them back. The branch manager just dismissed me, refused to look into the system stating I don't have an appointment, and gave conflicting information calling it 'invalid ' and 'NSF ' without providing documentation. The bank was withholding my legal settlement records and refusing to communicate. I got a letter stating it was an invalid check and will be mailed to me in 10 business days.
