Query: Poorly engineered Litter Pan Cover

I am disappointed with the product. It is unraveling at top of front panel where it latches. It was also SOOOOO HARD to put the metal legs into the rubber pegs. The holes in the pegs are too small. I had to enlarge them a bit with a screw driver. I wish I had my money back!
