Disgusting and repulsive customer service.

I have had an issue with MTN since last year August and till today my issue is still not resolved and I keep on being sent from pillar to post. I took a 36 months contract in 2019 December which includes 1GB day-to-day data and 1GB nightshift express, since from August last year I have not been receiving my night express data and whenever I call to report the issue they are telling me that I'm not provisioned to get night express data even though I explained to them that I have been getting night express data since from December 2019 till August 2021 when it suddenly stopped. I have logged numerous calls with them and their back-office department but still, nothing is being done to have my query resolved. The following are the latest 3 tickets logged by one of their team leads Jothika Abanna to their back0ffice department REQ***, REQ***,***. the tickets were logged on 02/02/2022 and till today I have not received any feedback from the people these calls were logged to. Besides Jothika's multiple attempts to get feedback for me from the back office department, they are not providing me with anything. This is the most disgusting and repulsive customer service I ever received.
