Pvr glitching issues

Pvr has so many issues. Telus has replaced 3-4 times in 4 months. Always have poor wifi for years. The technical department always says nothing to do with wifi. Today they tell me I have too many devices for service but I am paying for highest service. It shows iPads that are dead connected. Solution is to disconnect wifi on all devices. Cell reception so bad Telus said I have to keep wifi assist on or can't talk on a phone I pay even more money for

seems issues are at high use Olympics or sporting events or bad weather. Today the recording I was watching glitched and was unwatchable. Not many devices being used at that particular time so I did not believe this response. Two recording were taking place at this same time. So if pvr is recording then you can't watch a recording?

what is the real answer and I am unsure why I should continue to pay for equipment that does not work. really don't know what to do. Only option if Telus is not able to fix and now just tells me I am the issue, I assume I need to move to a competitor
