MTN has worse customer care service.

MTN has the worst customer care service. I have made a payment at a MTN store on 09 August 2018 using my bank card. 1 week later my line was suspended due to nonpayment. I then called the call center and was informed that my August payment was outstanding. I sent through proof of payment. Nothing had been done about it. I then went into the store to query and was told the specific department was closed and that I needed to come back before 17h00. I then contacted the call center a few days later and was asked to resend my proof of payment which i did. I Still did not get a response. I then went back to the store and left my documents for them to investigate. The next day I got a call from the store , saying that my payment has been incorrectly allocated and was being resolved. a few days later I received a sms from MTN saying that my query has been resolved (with a reference number). To date the matter has not been resolved. my line is still suspended . my account is still in arrears. Now its the billing department who is not rectifying the account and in the meantime I am being inconvenienced which means nothing to MTN.
