Terrible Service from MTN

I am absolutely appalled at the service I have received from MTN. At the end of August last year I put in a request to change over my contract to another name and to change the banking details (done at MTN Westwood). All paperwork and credit checks were accepted and I was told that from October it will be effective, however, no payments went out in October and November from either the old or new account. I had to go into the store both times to personally pay my account and each time I was assured that the following month it would be sorted. In December and Jan a Debit order went out on the 1st and being relieved that it had finally been resolved, I assumed I wouldn't have any more issues and was happy to let things slide. A little later in Jan I receive a message to say I have to pay an outstanding payment and thereafter receive messages to the extent of threats to report me to the credit Bureau for not paying. At this point, you can understand my level of confusion and frustration, especially since the Debit orders had gone out. I then went into the Pavillion store and the lady who helped said their was an outstanding amount from previous months which I then paid. I then requested to cancel my month to month contract as I no longer wanted to deal with MTN. I was told that my contract will take a month to cancel and will be effective as off 10/02/222. I was still billed in Feb and again in March and after calling again, I was told that my contract has not been cancelled. I can not possibly understand the level of incompetency with this service provider and how it takes this long to do anything. I require urgent attention and assistance ASAP or I will be forced to report MTN. I will no longer be using MTN and unfortunately you have lost a loyal valued customer of many years.

I await your response URGENTLY as I have reached my limit of frustration and patience!
