overcharging

I have been struggling for three weeks now on a query I have logged with MTN. My first query was on 18Aug 2015 about an amount that's way over what I should pay and my phone being disconnected. Ever since then I have been waiting for a consultant to phone me back regarding this query. In the meantime I have phoned two more times and sent an email to customer care and still no one has come back to me, and my line was disconnected for a second time. Only a reaponse the the email of apology. The apology does not sort my problem!!!<br> Every time I phone, no one can tell me where this amount is coming from. I even visited the branch in the mall and still waiting for a consultant to phone me back. <br> I will not be held responsible for this outstanding amount for I have not used it. Reason being I have a top up cellphone contract, and I have never used up my data on my ****le contract. <br> I've always come up for MTN when everyone complained about this problem, and now I am the one being *****ed by them.<br> if this service continues I will cancel my contract.<br> <br> 1st *** 18/08<br> 2nd *** 28/08<br> 3rd *** <br> <br> thank you <br> Charmaine Olivier<br> charmaineolivier88@gmail.
