Rymar Synthetic Grass Ltd

We purchased the Rymar tiles for dogs from Raymar. When we originally purchased, we over-ordered and returned some unopened boxes (We weren't permitted to return 2 open boxes). We were charged 20% restocking fee. My 6-week-old pups have since pulled up and shredded 12 tiles. I called and there's no warranty. It says it's for dogs yet little puppies are able to destroy it? No warranty!? Buy elsewhere! Total waste of $$$$.
