Poor service

I reported a ***** case in December last year with MTN(Mondo) after seeing a debit order from MTN on my account. I have never opened an account with them. I submitted the relevant documentation well. To date,they have not finalised the case. In all instances when I call,I am being told that the “matter is currently being investigated”. I have app**** for credit with credit providers who tell me that “you have a pending account with MTN that is in arrears”. I have been advised by credit providers as well that MTN needs to report the matter with the South African ***** and Prevention Services in order to clear my name from this debt. MTN has failed to do so,they even drop my calls.
