Product: Credit card or prepaid card

I needed to transfer {$10000.00} from my Bank of America Savings Account to my Bank of America ( BOA ) Checking Account to move to a new city to start a new job. With the click of a button online on Wednesday, XX/XX/XXXX, I mistakenly transferred {$10000.00} from my BOA Savings account to a CLOSED Bank of America Credit card carrying less than {$500.00} due. 
I called Bank of America ( BOA ) on Thursday, XX/XX/XXXX, to have the money transferred back to my BOA checking account. I was told by a BOA checking/savings representative on Thursday ( XX/XX/XXXX ) that I had to wait until Friday ( XX/XX/XXXX ) for the credit/debit in the amount of over {$9500.00} to post to my credit card, after which time the transfer back to my BOA checking account could be expedited in under 3 days. On Friday ( XX/XX/XXXX ) my closed BOA credit card showed a credit/debit balance of ( negative ) - {$9500.00}, the amount I overpaid. I called BOA on Friday ( XX/XX/XXXX ) and was told the transfer from my closed BOA Credit Card back to my BOA checking account would take 2-3 days. On Tuesday XX/XX/XXXX, I again called the BOA Credit Card Customer Service line in Texas at XXXX XXXX XXXX XXXX ( XXXX ) and spoke to an incredibly rude and combative supervisor named XXXX who would not provide me his last name nor a reference number for the call. XXXX told me ( THIS MAKE NO SENSE ) that because the BOA credit card account was closed and because the negative - {$9500.00} balance exceeded an arbitrary threshold of {$7500.00}, it would take BOA an additional 15 days on top of the 2-3 days I was promised to transfer my money from the closed BOA credit card back to my BOA checking account and that ( Jesses words ) the ball wasnt in motion during the previous week in which I had made calls to BOA regarding this transfer. Because XXXX indicated there was a threshold amount of {$7500.00} that could be expedited for a transfer from my BOA credit card to BOA checking in 2-3 days, I asked him to please just transfer that amount back to my BOA checking as it had almost been a week after my first contact with BOA customer service. XXXX indicated that he could not transfer any of my money on my closed BOA credit card back to my BOA checking account, that this matter could take 15-17 days for his BOA supervisors to review, and that it would take them this long to ensure this wasn't a money laundering scheme. I have been a customer at BOA for 20 years and have been working on an very modest academic/educator salary my whole adult life. 

This is ludicrous. I do not owe Bank of America ( BOA ) anything, and they can clearly see in their records the negative balance on my closed BOA credit card exists because of a simple online mistake, and that money should be transferred back to my BOA checking account. The BOA checking department states I am being given misinformation by the BOA credit card department, while XXXX in the BOA credit card department today said I was given misinformation by the BOA checking department. They all need to be held accountable and not be allowed to hold the entirety of customers money/savings XXXX for weeks at a time when those customers owe them nothing and pay fees for service. The credit card and checkings/savings departments at BOA should also not be allowed to be siloed so that neither is accountable for what the other does to customers if these accounts are connected by customer funds.
