Bank of America review: Checking account

My mother had a Bank of America checking account in which I was the only pay on death beneficiary. My mother passed away in January. I brought a death certificate and bank statement into the Bank of America branch on University Blvd. in Jacksonville, Florida (3535 University Blvd. West) and spoke with Jaime Mariscal who completed the necessary paperwork on January 28, 2021. Jaime opened up a new account for me to transfer the funds into. I was told that the longest that it would take to transfer the funds was 11 business days. On Monday, February 8, 2021, I contacted Bank of America's Estate Department to obtain an update. I was advised that it would be 3-5 business days to transfer the funds in my Bank of America account. I contacted Bank of America Estate Department again today and was told that it would take 7-10 business days to transfer the funds from 2/8/2021. I asked to speak to a supervisor and was advised that none was available but that one would call me back in 24 to 48 hours. I need these funds and the bank is intentionally dragging their feet. They are simply using my money unjustly and depriving myself of the benefit.
