Poor service an failed wifi cinbectivity

I am utterly disgusted in the serve received from Rain (the non contract wifi service provider). This whole of August 2023 has been a connection nightmare. I am their 5G unlimited wifi customer, paying R529.00 per month. My connectivity has been slow, with some Apps not playing at all (all of a sudden). This evening I finally retrieved the Rain contact center number and reached out to them. It's an 081 number. From 19h45 each time I call out my number, somehow the line cuts and cannot hear the operator on the other end. On my 4th attempt of calling at 20h00 I get the voice over of "we are now closed please call on Monday" - what ******* is that?! My account is up to date and I'm in the Cape Town coverage area. What is happening?
