Overcharged again!

MTN never ceases to amaze me as to how poor their customer services has become. As any sales person who is worthy of the qualification they hold should know is that after sales support and satisfaction is paramount for future sales. MTN has once again convinced me to cease all business relations with the organization. My wife took out a contract/upgraded her contract and was told that she would pay a specific amount well below R500.00 on her new contract. Our 13 year old daughter's phone is linked to this account. Knowing how 13yr olds are we decided to put a service usage limit on her number on 18 July 2015. In September she was invoiced R977.56 and in October she was invoiced R2860.75. Having gone to the MTN store in Greenacres on more than one occasion the problem still has not been corrected. We are continuously being told that a call has been logged. Its time to stop logging calls and fix the problem MTN. You have lost a few more customers this time around. Keep it up and you will go out of business.
