Requested my Contract to be Terminated but did not

I payed R1900 on the 25th of August 2015, then requested the Contract to be terminated as the Sim cards were not open. MTN then delayed to terminate and kept on asking me whether I don't want another package, they will do anything to keep me happy and still, they kept on delaying.<br> <br> At first they said since my account has been closed from March, I can use the airtime and close the account after using the airtime, but then I kept on struggling with opening the Sim cards, I even went to Bloem Plaza MTN Store in Bloemfontein but still coudn't get any help as the sim cards kept on saying \Sim not Provisioned: 2".<br> <br> Now what they tell me is that my account is 30 Days overdue and I must Pay that required amount. How can that be while I told them to terminate the contract by the end of August 2015?"""
