MTN DOES NOT CARE ABOUT THEIR CUSTOMERS!!!!!!

in a nut shell: a data bundle tab package was sold to me upon my upgrade. The consultant did not activate the limit set to R1. as she promised. the tab read 0 airtime / 0 data. my kids then activated my hot spot on my telephone to download. without realising that i they were using data from the tab??? i had no idea how that was possible as it read 0 data!! so i went into the MTN stor in (TOKAI - Cape TOWN) where i received the tab telling them that someone's account is linked to my account as i received a bill of R1300 and how is that possible if i didnt use or even have data to use??? - to my surprise im told that a customer has CREDIT with MTN and the kids downloading was a credit we were tapping into! REALLY???? this is such a CON!!! because why on earth was this not told to me by the consultant.. then another consultant says that its not something they\advertise"REALLY??? they get taught to CON you!! hence i have rejected this debit order bill of R1300 and will continue to reject it until this problem is resovled. The best part is that i have been waiting for 3 WEEKS for the \""manager to call me?? REALLY??? is their anyone i can speak to that will take their customers serious?"""
