Product: Credit card or prepaid card

XX/XX/2017 Hello : I have a complaint about some things Bank of America has done regarding my Visa credit card with them. There are many details, but I will summarize what happened to communicate my complaint to you. 
1. I had a high-interest balance at XXXX XXXX XXXX XXXX XXXX. I wanted to pay off the balance using a lower interest balance transfer from my Bank of America card. 
2. By phone I asked what promotional-APR deals were available on my account. An attractive deal was available, so I requested a credit limit increase to allow me enough credit limit to pay off the XXXX XXXX XXXX XXXX balance. 
3. I was granted a credit limit increase. 
4. I requested an {$8400.00} balance transfer to XXXX XXXX XXXX XXXX. It was processed. 
5. After more than the number of days I was told to allow for the transfer to be received, I called XXXX XXXX XXXX XXXX and found they had not received a balance transfer. 
6. I called Bank of America. The person said he would put a stop payment on the first balance transfer check and process a replacement balance transfer. He did so. 
7. Somehow, the stop payment did not work and XXXX XXXX XXXX XXXX received two balance transfers. This left me with a {$7700.00} credit balance with them. 
8. I had no idea at that time how they had received two balance transfers, but I felt absolutely sure Bank of America 's systems would not process a balance transfer that would put me over my credit limit. They must have seen a mistake was made and adjusted my credit limit to avoid an over-credit-limit situation. 
9. Since I knew I had one other credit card balance I was paying on, at XXXX XXXX, I asked XXXX XXXX XXXX XXXX two send the {$7700.00} to my XXXX XXXX account and I would lower another high-interest balance. They did what I asked. 
10. Bank of America did not contact me in any way about this. Weeks later, when I received my Bank of America statement, I saw the credit limit was less than the balance. 
11. Bank of America has now reported the over-credit-limit to the credit reporting agencies. 
12. Summation : I asked for an {$8400.00} balance transfer from Bank of America. They processed it. Then when XXXX XXXX XXXX XXXXXXXX did n't receive it, they put a stop payment on it, and processed a second balance transfer. Bank of America 's stop payment somehow did not work, so two balance transfers had been completed. Not knowing what had happened, but being sure bank of America would not process a balance transfer that put me over credit limit, I used the money to pay down another balance at another bank. 
13. Although Bank of America representatives freely admit Bank of America made the error, creating the situation, they want me to resolve it by trying to get the money sent back to through the banks involved, and back to Bank of America. 
14. I told Bank of America that I am the customer who requested one balance transfer following one request for a credit limit increase. Bank of America mistakenly made two balance transfers. And now, Bank of America expects their customer to resolve the problem, while they refuse to accept responsibility to resolve it. 
15. If Bank of America will simply raise my credit limit to accommodate the amount THEY charged against it ( without my consent ), this issue will be resolved.
