NEED URGENT FEEDBACK PLEASE!!!

I settled my account at Game at the end of August this year, since then I've been receiving statements with outstanding protection fees and interest but nothing is owed on the account. I have been fighting with their call centre agents since then, I've got 7 reference numbers already of calls I've made to have this sorted. I finally spoke to a Nicole who is apparently a manager there and she sorted it and I got a letter stating that my account has been settled and I have a zero balance (letter dated 21 Sept 17) but low and behold in October I received a statement once again with R0.72 outstanding. I sent an email with the letter I received attached and have followed up on that email 4 times and still haven't received feedback. I got another statement in November the outstanding amount now R31.72, once again called the call centre and what a surprise, no feedback when I was told the charges would be reversed in 48hr. I've now had it with GAME!!! I wanted to keep my account open in case I need it again but I no longer want any dealings with you. Please can someone call me about clearing/crediting the outstanding balance and CLOSING my account!!!!
