Terrible Terrible service from Rain

I lost internet last Friday 30 October 2020. Non of my devices pick my router up. (it tells me the router is faulty). I could not get hold of them telephonically. I reported via online support. They send a response that i will be contacted within 24 hours. No response from them. I phoned on Monday 2 November 2020 and was a ***** because no-one is contacting me. Then I received an email requesting to switch my router on (It is on). The they responded that I should do a hard reset. Which I did 20 times with no luck. I told them i took the sim card out and still the 4G and 5G's green light still go on at the same time. Which tell you there is something wrong with the router. Then no response on my 5 emails after that. On 3 November after 12 midday they came back to me stating they also think it is the router and that they will replace it. I had to confirm my address for the pickup of the old router and delivery of the new. It can take 3 to 5 days but is normally within 1 to 2 days. Which is ridiculous. When I placed my order with Rain in March I ordered it around 16:00 and it was delivered the next morning 8:00. After confirming my address he responded they will let me know when the new router is on its way. I've send 4 emails between then and now (3-5 November) asking why they ignore my emails and what now but still no response. I have an university student and a grade 12 pupil in the house who started today with his finals and I have to buy additional data for them to enable them to access there studies. I never before experience really problems with Rain but there is non or very little support from them.
