No Telus coverage

We recently moved outside of Golden, BC. There is no Telus coverage here. We have contacted Telus numerous times about having no service. We can't call out most of the time and we can't receive calls. Most calls go to voice mail. Telus advised us to use wifi calling. We cannot use wifi calling because our phones are detecting EXT. Only one bar on EXT. It never switches to wifi calling. We are trying to operate our business and missing calls from customers. Telus has basically told us to use wifi calling and we'll have to deal with it. We want Telus to waive all fees and contracts so we can go to Roger's which is in the area. This is beyond frustrating!
