MTN does not take customer complaints serious. Their service is just disgusting.

WHY IS MTN NOT TAKING CUSTOMER QUERIES SERIOUS???? It seems like everyone who works for MTN is programmed to just say "it has been escalated"....and just leave it at that. I did an upgrade on the 2nd of April 2020. From day one everything went wrong. I took up a data only contract (60GB). I have been only receiving 12GB for 5 months now. I have queried the incorrect provisioning of the data, on all the channels available and all have failed to resolve my query to date. The customer service is appalling. I need help to get out of my contract as MTN is clearly not prepared to resolve my issue. They have been debiting my account in full for 5 months.
