Failure to complete contract process

I tried to port my number from Telkom to Mtn. This first time I went to MTN Gateway and proceeded with the contract, which was approved. The porting of the number was not done as they had no stock of the phone I wanted for 2 months.

Eventually I decided to go to Mtn Cornubia and change my original choice of phone. Once again, I app**** for a contract and a number port. Once again the contract was approved (October 17). I was advised that the port was successful and it will go through in a few days. After those few days, I called the store and I was advised that there was an error and my port was scheduled for 1 November incorrectly. They were trying to sort it out, apparently. After I called again, they advised unfortunately I have to wait until 1 November. So I waited, another month. On first of November nothing happened so I called the branch, again. Then they advised that I was deleted from the system and they cannot sort the issue out. They were waiting for head office. It has been over a month and I still have not been sorted. Does MTN not want new customers? Furthermore, why was I not advised of any problems from the branch itself? I was always the one to initiate the call to query. This is rather disappointing and I will cancel all my other contracts with MTN going forward.
