Difficult closing Game store account

I went to a Game store to close my Game account. After speaking to an RCS consultant, she called the call center who gave me the settlement amount and told me that I'll get a letter stating that my account has been closed. I paid the amount on the same day (end of March). Two months later my account has still not been closed despite numerous phone calls to the RCS card devision. I have sent an email to their complaints department, but no response received. When contacting their call center, they mentioned that no managers were available to speak to me. I am at wit's end and interest is building in the inactive account. Very unhappy Game customer.
