Hi all, I am trying to remove a toilet seat and the two screws that hold it in place are stuck. The one on the left can be turned but won't come out, it feels like some of the rubber is moving with it, and the one on the right is not moving at all. I can move the toilet seat forwards and backwards and angle it to the right, but I can't get it off. I've tried different sizes and shapes of screwdrivers, but nothing seems to be working. The brand of toilet is Fienza if that helps at all
