Still no help from MTN 3 weeks later!!!!

Very short version, went for an upgrade, was very miss-informed therefore cancelled upgrade within 2 days, needed my old contract re-instated with my blackberry settings, and the upgrade charges reversed, it's been 3 weeks, countless queries, countless time wasted in the MTN Beacon bay branch where the manager Angie couldn't care less nor the staff there and my phone is still not working and the charges still not reversed. I need my email for business and have been without this since their stuff up, please help!!! The only step next I can think of is the ombudsman as I have no idea what else I can do. Any advice or help from someone senior in MTN would be appreciated, as so far the \service"has been non-existent and disgusting beyond words. Beyond frustrated. For the full version"
