FWIW, I used to be a manager in a customer call center for a wireless company. I would make one last attempt to call the customer care dept and calmly and politely ask to speak to a manager. The situation that you are describing is a case of front line employees following the rules a little too closely. They should want to keep your business (its expensive to have to replace customers). A manager would probably be more willing to work with you and have the authority to make that decision. If you get a manager or supervisor, keep emphasizing that you would like to keep your account with them, but that they need to help you out with this situation. They are not losing any money by splitting your account. Good Luck.
