Minor cosmetic damage to french doors just been installed

Hi all I just had new windows and French doors fitted. One of the bigger windows has a black mark on the inside of the double glazing it can't be removed from the inside or outside of the house. One of the seals on the French doors has a split of around 1cm Also there some small scratch marks on the outside.if the French door trim where the French doors meet, and minor ones on the inside in a similar place. I've paid for these windows etc already, but I have notified the company, I know it's cosmetic but still, I paid several thousand for new windows etc and I'd expect them to be free from scratches etc Where do I stand if he doesn't help rectify this? As I have my doubts. Thanks Mark
