Pathetic service from MTN

My partner and I are really ****ed off at the pathetic service from MTN... About 3 years ago she had a contract with mtn and didn't upgrade and cancelled it... Finally we realized it's time for an upgrade so we decided to go to iPhone at eastgate mall... There we were told we would have to pay an extra R50 to the contract that we chose all of this because mtn didn't clear her as she closed her contract with thm 3 YEARS ago... We thn went to the mtn store and was told they will not able to help us at all and we shouldn't even call the mtn service centre because they won't be able to help us either... So after much thought we decided to just take it and pay the extra R50 it's already been a day and we still don't have approval all because iPhone is waiting on mtn to do a credit check... I mean how ridiculous is this! Honestly... Really pathetic of u MTN.. If anyone is wanting a new contract phone, please don't decide to ever use MTN as a service provider coz they will disappoint you!
