Incorrect billing pending resolution for 4 months

I was billed and debited R146660.00 after disputing the charge as I was out of the country with data switched off and phone switched off. ( 28 hours of calls) <br> My average monthly account is between R1500 and R2000 on average and has been for years .<br> I requested that I pay my monthly average which I did and debit still was processed.<br> I have an email trail of over 4 months now and last response that someone would resolve was on 01 July and would respond by 02 July ( This has been the fobbing off for 4 months.<br> <br> This service to a good customer of 13 years is shocking<br> <br> Trust someone will respond as MTN as far as I am concerned is faceless
