PLACED ON CONTRACT WITHOUT PERMISSION-VERY IRRATE

I WAS PHONED IN JAN/FEB 2015 FOR AN OFFER WHICH I NEVER ACCEPTED TELEPHONICALLY, MY WHATSAPP, EMAIL AND FACEBOOK IS MESSED UP. LOGGED A QUERY WAS TOLD IT WILL BE SORTED, STILL WAITING AFTER EMAILS AND CALLS. TALK ABOUT NO SERVICE ON QUERY LINE 808, BATTLED A WHOLE DAY TO SPEAK TO SOMEBODY. I HAVE BEEN WITH MTN AS A PREPAID CUSTOMER FOR YEARS, NEVER HAD A PROBLEM TILL NOW. VERY IRRATE, WENT TO VODACOM TO PORT MY NUMBER BECAUSE I WANT TO CHANGE OVER, IT WAS DECLINED BY MTN BECAUSE THEY STILL HAVE NOT FIXED MY PROBLEM. CAN SOMEBODY PLEASE GIVE ME THE CUSTOMER SERVICE THAT I DESERVE AS A LOYAL MTN CUSTOMER. I WOULD LIKE TO KEEP MY OLD NUMBER, BUT IF THIS IS THE ROUTE I HAVE TO GO - CHANGING MY SIM CARD SO I CAN USE MY PHONE, THEN SO BE IT. IM REALLY NOT INTERESTED IN WHAT MTN HAS TO SAY, ALL I WANT IS FOR MY QUERY TO BE SORTED OUT SO I CAN MOVE ON FROM VERY BAD SERVICE!!!
