Fiber migration: Long-distance plan removed and $25 monthly increase

We’ve been moved to fibre, a forced move since we were happy with copper and our agreements and bills till last October.

Everything needs to be updated and we agreed, even if it was so difficult, to do the update. Old house, lots of issues. Since last week most of the issues have been resolved. A technician still needs to come to move the Optic TV service. Nonetheless, we are still receiving email and menacing letters, even registered letters to move before they cut the copper. It doesn’t depend on us. It depends on the availability of the technician , and we have to wait till mid May.
I called the support and told to stop sending those email and letters because we had three-quarter of our services moved already and it’s up to them to finish the job, not to us, but they said they cannot do anything to stop it till it’s fully completed. 

Plus they moved our phone line to fibre as well but doing that Telus as removed and changed our service. Before we had a long distance plan that was convenient for us now they eliminated the long-distance plan and they want us to pay $25 more

On the back of the letters sent to us,  it’s clearly written that the costs and the services we have will not be changed and we will not be directly impacted by this migration.

I already called the support three times but each time they have a new excuse.

The first one was we cannot do anything now, till the phone has been moved to fibre.

then, you need to call the loyalty department , where they could not care less of our issue 

and the last one was: “OK we can put you back on copper to give you the same service you had.”  
BS: we can’t go back to copper thanks to Telus forcing us to move to fibre because they are removing the copper in our area, so they wrote and told us.

It’s really frustrating to have to deal with this wall of incompetence.

Where could we have our rights taken seriously?
