Bank of America Worst banking firm I have ever dealt with!! Las Vegas Nationwide

A year ago I changed my business there for needing to change the name. Recently I have had a lot of charge backs from my customers. Wondering why, I contacted Bank of America and they told me my old business name was still on there! After going to multiple banks to fix this( over a month time lapse here) they told me I should just close out my old account and reopen a new one. I did this and having it cause problems with the IRS and other issues the old business name still was one my new account! I have lost thousands of dollars from customers due to this problem! BOA gave me the charge backs and I sent them the proper documents to get this resolved. Hearing nothing back from them I called back to check on the status and they explained to me nothing could be done now. I had argued back and forth that this was not my fault and something needs to be done. Again no help. I asked them again what the name was stating on peoples bank statements, again was my old name still!!!!!Two weeks have passed going back and forth and still nothing has been resolved. Regarding the charge backs I was told by 3 different people they could be fixed then the last person I called said they could not. Also 3 representatives told me my company name would be changed within 24-48 hours and still nothing has been changed. My customers are still viewing there statements as my old company name and I have to go and explain this to them all so I do not receive more charge backs. This has made my company look really unprofessional and also skeptical to my customers. I finally called again and asked them what the status was on the name change the last rep that I spoke to apologized for the previous reps and said I needed a form to fill out and then my name would be changed! Why have I wasted all this time and energy and the information I had been given by not just 1 rep but by 3 that there was no document that I needed to fill out! Their unprofessional-ism and miscommunication has ruined my hole outlook on BOA. I have recently changed and gone with someone else smaller company but way more professional. BOA has wasted not only my time but my customers time and my money. Really angry with BOA and how they handle things ( which is not at all. ) I can not even fathom how they could not understand a simple task to change the name! 1 year has passed and still not solved and on top of it all instead of changing my name to my new company name they somehow merged my old name with my new name and messed it up even more! How can these people be so incompetent?
