Cancel Data Contract

On 12/01/2015 I AGAIN lodged a complaint (attempt no.2) to cancel a data contract ***) that was not functional from day 1 (the sim card was returned to store within a week of buying the contract and numerous attempts were made by the store to get the contract cancelled). AGAIN MTN (Tim) responded quickly with a REQ (REQ:***) but when I did not get any more feedback I decided to phone MTN myself (again) and spoke to a consultant who refused to put me in contact with Danny who handled the complaint (attempt no.1) the previous time. I was told that the sim card that is required to cancel the contract (sent to MTN by the store as instructed after attempt no.1) has not been received ????<br> Well it is now a few months later, I still pay for a service which I don't have and still no firm feedback from MTN.<br> Lets hope it's 3rd time lucky.<br> <br> This is very frustrating, it seems like MTN does not care about small customers and just throw the problem back at the store every time.<br> <br> I shall definitely think twice before renewing my phone contract with MTN.<br> MTN PLEASE cancel the contract and refund me for the almost 19 months I have been paying for a data service which you did not provide
