MTN LIES FOR CONTRACTS

I added a new Contact to my existing one on the 24th of November 2021. Unfortunately non of the advertised add-ons nor the actual contract content was loaded correctly. I sent MTN an email on the 5th of December 2021 to ask them to sort out this problem. Since then I have had 4 Emails from them stating it has been escalated to the relevant department the most recent one was Yesterday. Everytime I send them an email I get the same reply and nothing gets sorted out its been 12 days since I logged the complaint and still no answer. Realizing I should have made use of a diffrent cellphone network, one with better customer service! If I phone customer service they say I have to wait for the relevant department to reply they cant help me!
