I find Telus support irritating.. The Chat AI is messed up and will try best to prevent you from chatting with a agent. Best way is to tell the AI chat bot you want to cancel and they will come back asap
Have you tried to use a Hard line or ethernet? With the telus Wifi i had the same issue and i still do.I have a 3G fiber but the speed on wifi is just 500 ish. :(.
