MTN useless as ever. Completely ***********

I have been a customer of MTN since 1998. I have had the same number since 1998. My average bill amount for the last 3 years has been R1450 monthly. In all these years I have never operated my device out of bundles. I have always had small limit on my account. As of 2016 I reduced it to R3900. This has always been more than enough. Now somehow. For the month of July. MTN have billed me R4964.22. No one can tell me what the billed amount is for or how I racked it up. But most surprisingly. No one can understand how I exceeded my account limit by over R1000. This is after I paid in an additional R1495 just so my account was not suspended As expected there call centre is a load of horse ****. The staff the work there are untrained and have zero logic. It is actually easier and more effective to talk to a brick wall. I have been into the store in Boksburg and they tell me I can only resolve this issue by speaking to a consultant on the 135 call line. This is impossible as I mentioned above. I certainly wish I could get a hold of an MTN executive and force him to try resolve an issue like this. I would like to see how he handles the situation. Then may be they can see the poor state of their organisation. I want them to justify the exorbitant cost for telecommunications, when this is the **** service you get in return.
