Billing of a Cancelled Contract

Good Day<br> <br> My name is Melisizwe Mabuya from Cape Town and my ID number is: ***<br> 083. I had a contract subscription with MTN, which expired in April 2015. I<br> cancelled the subscription after that and the contract cellphone number was<br> then converted into prepaid. The number I am referring to is ***.<br> <br> It is with great shock that I constantly get text messages that tell me about an account in arrears. The account number I had when I was still your contract subscriber was A***.<br> <br> I want to bring it to attention that I contacted MTN on 14 May 2015, the reference number for that call is ***. I was assisted by a lady who identified herself as Nontlantla Ngwenya. She told me that after paying the last instalment towards the accounts I HAD with your company, which I paid in May 2015, there will be no other payment needed from me and if indeed your company is honest in saying that calls from customers get recorded, you will hear me specifically asking her if there will be no other payment needed and her answer was NO.<br> <br>
