Damage caused by leak after windscreen leak.

Had my windscreen replaced on the 5th of July because of a crack on my original Toyota fitted windscreen. Prior to the replacement, I had no leaks, no rust issues, and no problems other than a cracked windscreen.

On the 2nd September, I noticed my roof lining was soping wet after being parked in the rain. I immediately went back to them to complain and managed to make an appointment for Friday (today) for them to refit it.

After denying the leak a few times, we were able to see where the leak was once the windscreen was off. And a rust patch on the metal of the car (under the windscreen where it is not supposed to be exposed to the elements), they told me that this rust caused the leak. However, I had no leaks before they replaced the windscreen. And nothing was mentioned about rust when the replacement was done the 1st time. (HOW COULD THERE BE RUST WITHOUT ANY MOISTURE EVER REACHING THERE.) I give them 2 stars because they cleaned it and tried to prevent further leaks. They also tried to clean the water marks of roof lining. However, you can still see slight water marks from the leak, and they refuse to take accountability for the rust caused by the leak.
