Shocking service and inability to assist

We have been trying to amend my husband's cell phone account from a business/corporate account to a personal account for the past 9 years. Every time we do our upgrades, we have to go through HELL to get it done, and every time we are PROMISED the matter has been resolved. GUESS WHAT!!!!!! It still have not been fixed. I have been on the phone to MTN for the past week, have spoken to multiple individuals, been transferred to many departments, and still NOBODY is able to assist us. No body even calls us back as promised! We have been loyal clients of MTN since 2005, yet they do not feel the same about us. This review here is the last attempt for MTN to get themselves in order, because our next step is to report them to both ICASA and the Consumers Council, purely for the fact that they are not willing to assist a client, and still cannot get it right after 9 years!
