Account **********ly Opened with My Details

End of November 2017, an amount of R700 was debited from my bank account by MTN. Knowing that I did not have any dealings with MTN, I called may back to reverse the transaction. MTN debited an amount of R1300 from account again on the 15 December, and I asked the bank to reverse the transaction again. Then on the 10 January I received a voicemail from MTN telling me to call them to make a payment arrangement. When I called them, I found out that there was an active contract that was taken on the 23 October with my details. I called their call center to try and resolve the matter, but I am not getting any joy from it. I was requested to send an Affidavit and a certified copy of my ID, which I did but the consultant told me that I have sent incorrect documents.
