Overbilling

I cannot begin to express my dissatisfaction and anger at the countless days that I have been inconvenienced by MTN pathetic service.I am quite surprised to receive such a heavy bill for May 2015.I can confirm that MTN definitely has (and always had) a problem with their billing system.They have never been able to resolve the problems and customers have been complaining about this for years.MTN makes the statement \MTN takes the satisfaction of its loyal subcribers very seriously and investigates every complaint on a case-by-case basis"<br> MTN are defnitely not serious about their customers loyalty.<br> I was billed R836 for May 2015.I recently upgrade to the Sony Z3 on a top-up 100.Monthly billing is R499 +105 (upgrade fee) but I must pay R836.Can someone please explain this to me?<br> And if you dail 808 you will wait forever.I went to my local MTN store but no-one can help me.I have emailed customer care but to no avail.Here is my ref no (#***8)<br> Now that the customers needs service everyone is on stike.Can you believe this.Can someone please call me <br> Wayne van Wyk ***"""
