Bank of America - WorldPoints Platinum Plus MasterCard Review

I decided to close my BOA accounts because the service provided by their employees and collecting agents is really bad. The worst that I had ever experienced. I was to pay off my credit card balance and they switched me to the supervisor for cnfirmation. The manager/supervisor (Shaun or Sawun) was rude on asking my account reouting and checking numbers. The background noise is really loud on his side. His attitude is bad and I can say he was shouting.
This is not the service that I expect since I do my own small business under BOA services. We never experience this kind of service before. Really, really bad !!!
