Thought I would update this. We had a cold spell recently and I had to use my heating. Switched it on in the morning only to find this:
Got really annoyed
Called autoglass, I don't think I managed to say 10 words and the customer support already booked a guy to come and check my windscreen two days later. He came in after 1pm, looked at the photo and an hour later I had a new windscreen fitted. Works great again
I know its only few days a year but damn it helps, literally 2 minutes and its good to go, dont have to scrape the ice, just sit down and warm up
Cant say a bad word about autoglass either, their aftersales were great.
