Service going downhill

Been a customer of Home-Connect for almost 8 years now and it seems that their service is going downhill. been battling with my internet for how long now, several calls to them, and yet no feedback. Logged a complaint about my outdated router that cannot old the band with. Have it for 8 years now and got it from Home-Connect wen first signing up with them. Phone on 03.05.24 and was told that some one will contact me. No reply. Logged a ticket yesterday. No reply.
