Unprofessional Service and behavior from MTN

I was contacted by MTN and they said my MTN acc is behind on payment of R2020,00, I then spoke to a customer care person by the name of Malik Ismael, and forward the two proff of payments I did, he told me that MTN will allocate the two payments and then correct the problem. A week later I received an sms grom MTN saying if I do not pay the outstanding amount then legal actions will be taken against me. I the emailed Malik Ismael from MTN trying to understand whatvthe problem is now but he never emailed me back or responded. I was then forced to do another payment of R2020.00 so how MtN owes me money.

I want to express my upmost dissatisfaction to this bad company MTN and there rude and unprofetional customer care representatives, I will now take legal action if MTN is not returning my money back to me asap or respond to my complaint, I know I am small against MtN but surely ants can make a diffrance if we work together.
