Pathetic service with no solution

Good Day MTN,

I have been a loyal contract customer since 2010. I have never had a problem when I needed to upgrade until now. 11 Years later I have been now been told that my initial contract I took was with my old company which I now longer work for. My contract falls under a Business contract now and since I have not been migrated onto the new system there is no way forward. This supposed migration was suppose to be done by last December. I contacted MTN via Whats App on the 9th April and I am still waiting. I got a response say #wegotu I am not sure what that is suppose to mean. This is not the type of service I expect after 11 years with MTN. Upgrading has never been so difficult before.
