Poor Service

I have already canceled two of my 3 contracts with MTN on the 19 July 2020, and I regrettably decided to keep 1 line. Firstly, the day I canceled I spoke to a consultant who advised me that the amount reflecting on the system was incorrect and that MTN will ensure that my billing will be correct. However MTN incorrectly debited my account. I called and logged a reference number and I was told by the consultant that the billing was incorrect and he will escalate to the relevant department to correct the billing and fefund me, which would take 24 hours. This was not done leaving me to call and follow up with MTN. When I requested the consultant to update my monthly payment to cash she advised that she can't because the system does not allow her. I instructed her and MTN not to debit my account and that I will process payment in store or via eft with immediate effect. She could not even provide me with the amount due for my next debit. She seemed less interested to assist me and asked me to contact customer care for any escalations I have. I asked for her Manager to contact me, and she advised that she was not available and that she will ask Narisha to call me on my mobile number ***. Further with the upgrade, to date I have not received the 20Gb data on both lines ie I upgrade to the 2 for one deal, this was done last week. It is clear that MTN does not care about their customers, have systems and people who are not enthusiastic about assisting and listening to customers, and cannot deliver on their commitment. I will not refer or recommend MTN to any person or individual who settles for anything less that what they deserve for what they are paying for.
