I'll ask about this for you when Im at work tomorrow, and try and find out what will happen etc.
Been a while since I've dealt with anything like this as I'm in a diff dept now, but I'm sure there is a department that specifically deals with damage to property caused by the muppets that do the installs.
I'll see if there is a direct number so you can call and avoid the indian call centre (i take it that's what you meant by nobody undersanding english??)
