MTN bad service

I had a contract with MTN and when it came to an end, MTN called for an upgrade. I told the lady that called that I could no longer afford R200 contract instead I opted for the R150 contract. What MTN did was to debit over R350 from my account, the amount we never agreed on.

Another issue I had with MTN is that I have requested over 5 times to change debit order date but that never happened. Each time they promised that they have changed but they never did. Instead now they debited mire than double the amount I agreed to. I regret having anything to do with MTN.
