Bogus Account

about 2 years ago I went to MTN Northgate to apply for a cellphone contract, I went through the process and filled in the forms. when the lady that was assisting me tried to do their verification's she she couldn't, apparently their systems were offline. she said it could take a while so I left as she promised me that she will let me know as soon as they are back online to finalize the application. 2 weeks went past and i didn't receive any call so i went back and i was told the consultant had moved to another branch and all her accounts were with her so i left it there and went to apply with another service provider. to my surprise they started debiting my account for a cellphone contract i didn't have. I went back to them and they advised me to go do an affidavit stating that I had not signed for any contract and have not received anything from them and I did, the manager said they will sort it out. to this day they never did. Now they handed me over to heir debt collectors and blacklisted me for a contract I don't have. I have been to MTN many times to try sort this out but they just cant be bothered. and looking a some of these complaint one can see that they just don't care.
