No internet connection

I am very upset with my situation. A few weeks ago I logged an error regarding the original router we received in Feb 2024, as it was freezing and didn't Wana pick up 5g. They kept telling us to reset etc and eventually only 4g worked but router was still freezing. Anyway heard nothing from Rain and then CCD or some other courier contacted me to arrange exchange of routers and I told them I am not aware about this as rain didn't call me or email me to say they exchanging. Anyway they came to exchange Friday morning just b4 10am. J called in to tell rain they said it's pending on their end I should be connected by 2pm called back and had to explain my story again and again to be told my issue has been escalated and I shud have internet in 24 hours. Called back yesterday and was again told it's been escalated and I shud had my internet restored yesterday. It's Sunday 10am and still not internet and I work from home so can u imagine how upset and stressed I am when I did not ask for an exchange I only asked use to sort out ur stupid router that was freezing and giving us the most intermediate connectivity 1 minute it's 30mb and the very next second poor connection on like 8mb. I am really not happy with the way things have been going and it's only 3 months with rain and I have had multiple issues and now basically paying for internet that I have not had for 3 days. I just laugh at the consultants coz they tell me the same storey over and over eish.
