New EE hub has so many problems

[CWDW]

Since updating my old BT hub to a new EE hub we have had nothing but issues. Television freezes with bright flash of light on screen. The new digital phones I got from BT do not seem compatible that I have had to ask they stop my phone service. 
they told me the problems outside but then they said no yjsys not the problem and say we have to have a factory reset on our hub. I wasn’t happy with this as I spent a long time connecting my appliances. 
I’m totally fed up and unless they change their useless hubs I will be going elsewhere for Internet and phone. 
they also take over 30 minutes just to answer the phone and the calls are total waste of time the staff don’t seem trained to fix issues they just guess. It’s of money each month for a poor service.

@JimM11 There is a reason people invented Wi-Fi. 

I would have to go though a flight of stairs, and 4 walls to connect my TV by Ethernet.

And to answer the next question coming, the one about how strong is the wi-fi signal reported by TV, it's 4 out of 4 bars.

All I am asking is a way to report bugs in the software. Many reputable companies have such mechanisms.

@Woyteck Nothing will be forth coming question wise, you may wish to try doing as you need via EE complaints!
