MTN not able to reactivate fixed LTE sim

My fixed LTE home line has been disconnected since the 23rd Jan 2021. I have called MTN 16 times, I have been to the branch 3 times and nobody can get my line activated. In the meantime I have to purchase bundles from a different service provider to work. The call centre agents brush you off like it's not their problem. Nobody gives you feedback on tickets logged. I have paid for internet I have not been able to use. The level of service as well as the turn around times have just been pathetic. All I want is for at least one person to help me and get this resolved. Once that is done, I will never call MTN or go near a branch again.
