Incorrect billing

Good day,<br> <br> I have initially requested that two of my contracts to be cancelled. A month later I am still billed for those. I call for days on end ,and the phone just rings and then dropped. And last month I was billed incorrectly and was unable to open the detailed Invoice , queried on e-mail as calling is pointless, no response still. Again this month same happens and numbers I DO NOT EVEN OWN are billed.<br> <br> My boyfriend had also purchased an Iphone three months ago with the same network and exprienced fustration from the word go. With his phone being blocked and had to go to MTN in order to make use of his cellphone. They increased some limit that was preset, we enquired if that will affect his regular monthly payment, the answer was a consistent no each time. Until recently he was informed that he owed MTN a sum of R689, clearly the amount had been accumulating and shows as a diliquent payer in the background thereof affecting his credit record.<br> <br> We went to the MTN in the V & A Waterfront enquiring this, we were informed about unbilled and billed account, which was news to us.Nothing was ever mentioned the contract about this or explained by the Sales consultant.
