Rain Network Problems

I have been using rain for the past 1 year and have never had problems with their network, until last week (5th May 2021). My rain lost network and I called them telling them about my issue, they promised to fix it and that they will escalate the problem. It's the 14th May 2021 today and nothing has been done. I am using the unlimited 4G of which I pay R479 every month and now I am forced to buy data for another network as I am working from home. The service is very poor, I always go through the same settings when I am calling them.
