MTN horrible customer service

My nightmare with MTN. I don’t even know where to begin. I have had a horrible experience with MTN in the last 2 years. I first tried to claim from their insurance, I ended up waiting for almost a year for them to replace it. For almost a year I was paying for a device that I wasn’t using. I then cancelled my contact with them. I’m now a prepaid user, yesterday I bought data for R999. It converted it to midnight express, meaning I can only use my data between 00:00 and 5am. I tried to call the useless customer helpline, but no one could help because my account still reflects as a contract user and when I get transferred to contract helpline, I’m told my account is prepaid they can’t assist. Now I’m stuck with data I can’t use. At this stage I’m ready to leave the network all together. Horrible customer service.
