Bad and inconvenient service

I spoke to a Carmen Maistry from retention ref *** in April and she upgraded my number as the previous contract had expired. Previously I was getting over 300Gig anytime data, to my surprise I am out of data today, 5 June 2024, I called in to confirm my package and I only get 200Gig. I would not have agreed to getting less than what I previously had as I work from home mostly. When I called contact centre to get recording, they referred me back to the department, then the department refers me back to customer care, then customer care is referring me to an MTN store for a recording that will be emailed to me!!! Does this make sense? Please assist. Also the network has been bad in the Nietgedacht area, can this be looked into?
