MTN has really poor customer service

I took out a sony Z3 with MTN direct via the call centre, i mentioned that i would like to port my number as i was moving over from Cell C.. everything had went through i received my phone 4 days later. A NEW NUMBER WAS ASSIGNED TO ME, i then made a complaint and i was told it couldn't be done now so i then returned the phone within the 7days stipulated and asked for it to be cancelled immediately and went into autopage and took out the phone with them.<br> i now have a contract with autopage paying R399 a month for my sony z3 compact, however... i was debited R654 for March and now R1194 for May by MTN besides being debited by Autopage.<br> <br> i have sent over 5 mails to MTN customer service explaining my concern and i get a poor response 4-5 days later with no clarification or way forward.<br> <br> i have now reverted to sending mails in languages i don't usually use, and still im not getting any assistance with this regard.<br> is MTN personnel competent to assist me? i have asked for somebody senior to assist me but this hasn't happened or is my concern of low priority that its just being brushed aside.<br> <br> the funniest thing is, i ported from Cell C thinking MTN would be better for me.. i was wrong...
