Mtn Customer care non existent

Mtn has staff that do not know their products or their processes. I took out a month to month 30gb mobile internet package. I asked for 3 months bank statements so that my account could be debited. via debit order .Mtn suspended my account the 1st month because their debit order didn't go through, they don't know how to process a debit order. I paid the outstanding amount in cash in early August. I have still not received my data for the month of August. They owe me this data as it was their fault that debit order didn't go off. ,Regardless of how many time you dial their customer care nr 083 135 or 135 it goes unanswered. Different branches gave different excuses why their debit order didn't go off. I have since taken out a package with the competition and will be cancelling Mtn soon. The competition debit order was processed and is working fine. Mtn month to month SIM date is R215 pm for 30Gb anytime bs Telkom SIM data 80Gb anytime + 80 Gb night data @ R199. Telkom deal smashes Mtn's pathetic 30Gb only and at a higher cost.
