Telus installed fiber optic beyond easement without permission

[wireless]

Telus came to our property and asked that they will be installing fiber optic on our property.
I asked them that I don't want the easement to be extended and that if they will be installing within the current limits?
They assured me that they will stay within the limit (6 feet).
When trying to build new fence (old one was gone when Telus came), the markings show all of the Telus installation is beyond the 6ft easement line.
Also, the owner of the house did not sign the papers for installation.
It has been already installed and has significantly reduced property where we can build fence etc. because we have a corner lot house.

I need to build a proper fence for for house and a good portion of my yard will be gone if I build after the new Telus lines.

What actions can I take to remedy this?
