Home-connect is USELESS!!!!!

Over the past few weeks/months I've had nothing but issues with my connectivity at home. Every time I call Home-connect, we go through the same troubleshooting process & then my connectivity is fine for a little while. Eventually one of their technical staff said I should get a new router as the one I have is old - it's the one I received from them when signing up in 2019. I ask which brands they recommend & TP Link was mentioned to me. I have an existing new TP Link router at home which I then connected. However every week I have the same connectivity issues which I am sick of now. It impacts my ability to work from home which means I need to go to the office in order to work. This is costing me in terms of my time & money & it's just frustrating. Rest assured that I will be switching service providers even if it costs me more.
