MTN NOT fulfilling contract obligations and Misleading

I took out a business contract. The contract details stipulated the following: MTN-Made for Business M - 1.5GB + 200min Bonus - 1 000 On-Net MIN - 6.5GB Anytime Data - 5GB TouTube Data - 2GB WhatsApp Data

All for R389 PMx24

I queried the person that helped me, on the bonus 1 000 "on-net" minutes and she assured me (multiple times) that the minutes are for any network. So I took the great deal.

After I got the contract, I noticed that the bonus minutes were limited to only MTN numbers and that for the past 4-5 Months I have not been receiving my Youtube Data. I have been trying to sort this out for about 4 months now and it is still not resolved.

I feel MTN was misleading on the wording of the minutes as I also looked everywhere for a definition and I assumed the person working for MTN would know what they are saying,

Apart from the minutes, I have still not received the YouTube Data that was part of my contract and MTN still takes the full amount of money every month. Each time I I call MTN or go to one of their stores, they are unable to assist me, they just say that the query has been logged and I have to wait.....We are on 4 months, how long should I be waiting?

The only reason I have given MTN a 2 star is because the person in the MTN shop is actually trying to help me, but she is unable to take the matter further.
