I am angry at the service I am getting

On the 25th of September, I upgraded to a 40/10mbps, now I'm trying to watch TV and use my phone, but I'm still getting a buffer. Mind you I'm right next to the router. I try to talk to the 24hr service and I'm not getting any assistance. Like I have resorted to this platform, cause I also work in the fiber industry and I I'm ****ed.
