Unresponsive service provider

I have had a WIFI line installed about a month before lockdown. Being forced to work from home i depended on my connectivity to be up and running. In the past month alone i have had so many down time that i had to hotspot from my phone costing me even more money. Its been two days now and im using my phone to hotspot so i can work this is truely unacceptable as when its time to pay im not going to pay minus the days i never had connectivity im going to have to pay full price. Get services up or technical support is an absolute nightmare at the moment. What does this mean 2 consecutive days no data!!!! your issues are creating problems for me and i dont think its fair that i will be getting billed full. Had Telkom and they gave me issues i ditched them is there any service providers that is trustworthy
