MTN Customer service sucks

MTN mobile is the worst network provider when coming to solving clients queries. MTN owes me money but I am being sent back and forth like a yoyo. After 14 days of waiting and calling, I am told that a credit was passed on to the account not my bank account like I was told it will reflect after 7 days. I have been waiting for more than 7 days and when I call I am being told I should wait another 7 days for a refund,now really?. I cannot wait another 7 days,the initial 1st request was for a refund. I was never told they have to make a credit then a refund,I mean where will that credit be sitting cause I don't have a contract with MTN anymore, it clearly shows that had I not have called I would still be waiting till kingdom come wondering what is happening . Because no one actually provide feedback to the client, which I find it to be very unprofessional. I am very disappointed in the way this matter is handled,when I have been such a loyal customer to the network. And the wait continues.....
