Breaching of contract

Poor service MTN-BELOW was the problem. evrybody!, they have done NOTHING YET to solve the problem,i send mail after mail,with NO response from MTN. they advised me to our local MTN office,but they said only head office can solve the issue.<br> <br> <br> 06.07.2015 upgraded contract to 50 and 100 topup. (2 x numbers),they changed the 100 topup to an open billing account. I emailed MTN,PHONED THEM. NO reply from them. MTN told me yesterday that Quadrant Mobile basicly do the uprading. You do on behalf of MTN.<br> my 50 topup anytime is correct. Its the other number that they must change to a topup and not an open account. I have recorded the deal on mentioned date of contract and asked MTN 3 times that i do NOT want any exstra charges. Both must be topup.when i made this deal,the amount was supposed to be R149.99 pm. They deduct R218 pm. ????? This is ***** and breaching of contract what they do. The worst service!
