I would call Rogers, and ask to speak to the Escalations Coordinator. Each area of Rogers Cable has one of these individuals. Their role is to manage complex or costly issues, including property damage.
The advantage with dealing with Escalations is that you're given a direct number and/or email address to reach them--no waiting on hold, etc. This person will send a manager who will assess the damage, and work with you to have it repaired by a licensed contractor at Rogers' expense.
If Escalations doesn't resolve your problem, then ask to speak to the Office of the President. However, I'm confident that Escalations will get it done.
