Where is my Black Friday bundles????

In November 2019 I signed up for 500 min and 30gb of data per month for 24 months on the Black Friday deals that Vodacom offered. Everything was fine and it was loaded monthly without issues. Then in August a consultant of Vodacom called me and offered me an upgrade on my line. I told her I do not want a phone as I have a business phone that I use but she can upgrade my contract to a sim only contract. I specifically told her that I want NOTHING to change on my current contract and I still want my 500minutes and 30gb data which I signed up for. She assured me that nothing will change and all will be the same. In September I noticed that my 500 min and my 30gb data bundles were not loaded. When I called Vodacom I was sent through from one consultant to another. I was promised by all of them that my query would be resolved and my data and minutes restored. It has now been more than a week later and it is still not resolved. I escalated the matter further but again nothing is being done. In the meanwhile I have to purchase additional bundles etc to avoid getting a huge account by the end of the month. I want my bundles restored as per the CONTRACT that I entered into with Vodacom in November 2019!!!! I have proof of these contracts and that they were loaded to my main contract.
