Mtn is ridiculous

Mtn is one of the most terrible network providers I have ever dealt with, I have a cellphone contract with them for 3 months now and no debit orders have been done for the installments, when I called to follow up I was told by one of the consultants that I must not stress my installment is only going out on the 3rd month, on the 3rd month no debit order went out again, so I called the customer care line and they said that the consultant captured my details incorrect and the contract is in arrears they then scheduled a date for the arrears to go out on Monday, and once again with mtn's **** service nothing went out, when I went in the store I spoke to another consultant and they was extremely rude and trys to say that this is my fault and not mtn and asks me to pay cash. I will never advise anyone to use mtn as they provider and they system and service to customers is pathetic
