Reported damage October 2023, still no resolution.

Looking for advice on how to get an issue resolved that I reported in October 2023. Trying to get Telus to come and fix some dagame that occurred during installing of fiber cables. Finally in May, 2024 I got a technician to come out and view the damage. He acknowledged that the installation was done incorrectly, took some pictures, and told me he would get back to me after talking to his manager. He even gave me his business card to follow up with him. I tried to call and text the number on the card but haven't got a response. I tried calling customer support AGAIN but every time I call I have to start from the beginning and explain the situation and I am told they can send a technician out. When I tell them that a technician already came out they schedule me for a callback to do more investigation but nothing ever comes from the callback because it's a new person and I have to start over again. I even tried escalating the issue using the Escalate to Manager form on the Telus web site. On the form they say that you'll get a call back within 1 business day but I did not get a call back. I am going in circles. Feels like Telus is just hoping that if they ignore the issue then I'll just give up. What can I try next?
