No record of us on system but we get listed!!!!

This is the second time I'm writing a report regarding this CRAZY matter. A couple of months back MTN listed my husband due to non payment of an iPad that we got from them. The bizarre thing is that MTN claims to not have him on the system, but somehow they gave him an iPad. We have on numerous occasions tried to make payments towards it and on those occasions we are told that he is not recorded on the MTN system! Now we get listed due to MTN's negligence. This has hindered us from making some major purchase and its not even our fault! The last communication we had from MTN was that it acknowledges that we have lodged a complaint. BUT THAT WAS MONTHS AGO!!!! You guys are seriously killing us here. Can you please sort this out ASAP because your negligence has interrupted our lives enough already! We can't even buy a house thanks to you. I really feel like cussing you out right now. This has gone on for long enough. The problems that you are experiencing as a company shouldn't have to affect or spill out on your customers. Right now we just want to get this sorted so that we don't have to deal with an unprofessional company that seems to be losing its edge like you!
