MTN SA *****

If I could give -10 stars I would. MTN SA has become one of the most ******* companies I have ever dealt with. I have not only had ***** on my account which I am trying to sort out , but in addition to this I have had four different people phoning me to process my upgrade which is due ( which I definitely will not be going ahead with) and each time I ask them how much my new debit order will be they drop the call !!!
