MTN Care's Less

I have been querying irregular billing and contract information from December. I have logged calls with no response and when querying my ref no, it gives me another call logged and reference numnber. Also dialled 135 to chat to billing dept/escalations/customer care and nothing. Tried emailing issue to 3 people at MTN stores to assist and nothing. What is the point of sending emails and logging calls if your just gonna be ignored. Wish i could port my numbers to another Cellular provider, cause MTN is deaf and has no customer care. Why is there never a reply... Go else where or stick to pay as you go. Never contract with them, you'll regret it should you need to get in touch.
