getting almost daily calls from telus

That sounds like the scammers that pretend to be Telus are calling you. The random numbers, the rudeness, etc. is all consistent with the scammers. There is no way to get them to stop calling as they are typically overseas in India. Telus and Koodo have Call Control that filters the vast majority of those calls out. If you have phone service with another carrier, you'll have to see if they have a similar feature, though at last glance, it's not likely they will.
