Worst Service from MTN

I had a data contract with MTN since 2020 and everything was fine I got what I was promised then last year July I upgraded I got what I was promised till November.December my date was reduced I called almost on a daily basis I was told that my contract is a 40gig day and night instead of 60gig day and night, I’ve sent emails,called was even sent to the Menlyn branch to get recordings and ya guess what I got ???? nothing and I called on the 3rd of March for cancellation and I was offered a better deal Which was 60gig day and 60gig night. They loaded 40 gigs day and 40 gigs night but they didn’t load the remaining 20 gigs for each. Whenever I call they promise to load it but they never do. I then have to call again multiple times. This has been the worst and most draining experience I’ve ever had with any company.
