Vodacom Fiber - Where is your after Sales Service.

I recently made the decision to join Vodacom Fiber after it became available in our area. I signed up for the most expensive personal package, as due to Covid, I am required to work from home for the unforeseeable future and I was hoping that this will suffice for my work and personal home requirements. It worked perfectly for the first 3 weeks, but for the last two months I have had untold issues and problems - mostly related to poor speed performance, that is if I do have fiber. I have logged numerous service requests at the call center, but every time I get informed there is was an area problem and it is now resolved and then my SR is closed - but still I have issues. I hardly ever have speed above 30mbps, usually it is single digit and although I should have 100mbps - and it is only being used for my work. My issue is, there is no after sales service at Vodacom fiber, calls are logged and closed but issues are not resolved. I am hoping that this will serve as a warning to others.
