Wanted to repair a 20mm deep cramp on the driver side of my windscreen which appeared due to low temperature but i've been refused. Man in the office says it's to small to repair and even does not look like a star and are not able to fix it. Not able??!!. They wanted to replace it only. I don't want to wait untill it will get bigger size. I want normally pay for the service. Obviously it's better to repair than buy a new one. Where are my rights? So what do they deal with?? Why do they exist?
