Brush strands found in focaccia

I purchased a cheesy garlic focaccia which had a large umber of plastic strands under the cheese. They seem to have been from a brush that was used on the focaccia. When it was reported there wasn't even an apology. I have taken pictures of the strands that was found on the focaccia. Further to that, when I used to purchase this previously it was the size of a large. In recent times it has been reduced to a medium. The quality and value for money seems to be diminishing.
