POOR TREATMENT & MISINFORMATION

In December I purchased a data contract with MTN. I got paid earlier in the month, knowing that my Debit Order would only go off later in the month, I then went to the store to make a payment. To which I was told I am only due for a payment on the 1st of February. My line is suspended and they refuse to give me access due to misinformation on their end. I've tried to explain how this is due to no error on my end, but they refuse to understand. Such terrible treatment for a new customer. Extremely unhappy!
