******* and exorbitant charges

I called MTN retention’s area in early December for an upgrade. Soon after I was told that I qualified for one with a fee of R350 - on a recorded line!!! I spoke to Marvin Mabuza. I was then asked to collect a device from a branch which I did - after having to visit the branch twice and have several painstaking calls to MTN and the branch staff. I also called the call Centre a and was told that my monthly charge was to remain the same. Needless to say, not long after, I get a statement from MTN with a 200% increase on my monthly subscription!! I was never presented with an increased monthly fee, I was not given any documentation to look through and even when I called the call Centre, I was assured of a monthly charge that was unchanged!!! I have been waiting for over a week for a response from MTN and it appears that they don’t actually care or want to understand the issue and they are purposefully delaying the response. This is ******* and unacceptable from MTN !!! Extremely disappointed!
