MTN has no sense of customer service!

I took out a contract with MTN on TopUp but it was never put on TopUp but instead put on an open contract without my knowledge. The data limit exceeded 2 months ago, and all my contracts were locked because of a R5000 mistake on their side. I called them and it is now 60 days later and all the phones are hard locked. I spoke to Managers, Team Leaders and just random Admin Staff from MTN. <br> All I get is promises to pass the R5000 credit. My account is paid in full, but the R5000 credit is still not passed. I am now sick and tired of this nonsense, and want to warn all South Africans not to do business with MTN as they don't have any customer service. Just promises.
