MTN Contract seems like a ****:Incorrect allocation of minutes,data,sms.

I upgraded to the mtn black friday special package(R139 per month) telephonically on 29/04/2020 which was a promotion being run by MTN during lockdown. This included 5.5GB anytime data, 5.5GB night data, 150 anytime voice minutes and 100sms per month. Calls are recorded so they have proof of this and I specifically asked Morris to repeat the full allocation to me, which he did. Lo and behold, I was not allocated this amount. I only received 1.49Gb anytime data, 100minutes and 50sms. I reported the matter on 17May to them via their messenger app as well as via email. Their feedback today is as follows : you have been provisioned accordingly. (their reference: ***). But I have still NOT been allocated the correct amount as per my contract. Also I upgraded 3 other contracts to this special and none have been correctly allocated. Smells like a huge **** to me! And being their loyal customer for about 12 years, this is so infuriating!
