MTN CUSTOMER CARE IS ZERO

I'm now so frustrated with MTN!!! They have the worst possible customer service I've ever recieved. I upgraded on 9/11/2021! Was supposed to recieve multiple benefits for my upgrade, but recieved NOTHING!! I made contact with them multiple times about this issue. Here and there someone said they will return with a answer within 48h. It NEVER happened. This morning I recieved an SMS stating that my benefits l, which I never got, expired. I spoke to 8 customer care workers and 1 at head office. No one could assist me! They rather got very rude. And now I'm starting to get very rude. We payed and pays alot of money to this useless company for years and to top that, we do not have signal in our town for most of the time!!! I will be changing networks and not support this pathetic company anymore!!!!
