Product: Debt collection

I used to have a Bank of America XXXX XXXX account that was close on XX/XX/XXXX after that my merchant account was limited to access. When this happens Bank of America merchant services told me that they will keep my last XXXX payments ( {$730.00} usd ) in hold your for safety of any case of client claim and they will be release in 6 months ( middle of XXXX ) I received a chargeback ( client claim ) for {$700.00} usd in XXXX XX/XX/XXXX and they took from my business account even when they have {$730.00} usd already in hold for this cases. I call the Bank of America merchant service to see how I can send the documentation Prove of the transaction to show them that the client was agree with the charge from the begging and the client doesnt has the right to dispute. I ask the for help because since the account was close I didnt have the access to answers and see the client information to answer the dispute. I send them a letter given all the explanation ( I will attach here ). In XX/XX/XXXX I make a call again to ask how will be the process to release the {$730.00} usd that they put on hold from the beginning and the said this will be on XXXX call us back XX/XX/XXXX. I do the call at this date and the make a request of release and said wait us we will be contact you ( never happen ). In XX/XX/XXXX I received a new charge back for a client {$1900.00} usd and I call them the same day to ask for help again because again I didnt have the chance to get in the portal XXXX XXXX to answer the dispute with the documentation that I have. They said that they will make an escalation and with for they answer ( never happen ) they never call me back I lost the case because the time end and they never give me the way to send the documentation or even answer the dispute. They send me a letter saying that they not approve the releases of the founds {$730.00} usd because I dont meet one o more of their qualifications ( I attach this letter ). 
I XX/XX/XXXX Bank of America make the decision to end all their relationship with me sayin that a Im a risk profile not longer aligns with the banks risk tolerance, so at this point the close everything but they still allowing my clients claims ( illogical ) trampling on all my rights and those of my company, denying me the opportunity to have a way to answer the complaints and send the required documentation making me lose my reputation and my money. 
When this happens, I call again to find out what will happen to the money that they have on hold since XX/XX/XXXX and they inform me that now the amount that I have on hold is {$1400.00} usd in a reserve account ( {$730.00} on hold from the beginning and {$700.00} from the dispute on XXXX XX/XX/XXXX last time I had access and was able to send the documentation, I won the case and this added to the balance in favor ) I said ok so making counts I own you Bank of America merchant services {$1900.00} + {$300.00} = {$2200.00} usd less {$1400.00} that you have on hold I own you {$760.00} usd to cover the entire amount for clients claims. I dont have a relationship with Bank anymore as you decide so please give me a way to pay you the {$760.00} usd that I own to finish this because as you see we have almost 1 year ( since XX/XX/XXXX ) trying to end with it. After talk with many departments ( all that calls was recorded for quality purpose ) they said we will send you to the collection. 
I said what?? Its not fair because Ill being given my face during almost one year to pay and solve all the situation I am here at the phone asking for a way to pay the {$760.00} usd that I own you and you will send me to the collection because you the most important bank of the United States doesnt have or know they way for me to pay. It doesnt have sense. 
The last agent that I talk said go to a branch and pay there, I went there the last XX/XX/XXXX talking to the business account agent and she said I am not available to receive this money because I dont know where I have to put it on. She call to merchant services and they do the same transfer her call to many departments without solution What I am claiming Bank of America merchant services give me the way to pay the {$760.00} usd that I own and not send me to collection because they already They violated all my rights and those of my company, denying me the opportunity to respond to the claims and now they also violate my rights, making it impossible for me to make the payment on a regular basis, sending me to collection, affecting my credit history. I can't accept it, it's not fair, it's a violation of all of my rights. 
Please I ask help me to solve this situation as soon as possible. 
Thanks in advance
