The rack was fine at the beginning. Then 1 wheel bent and it sat lopsided. Dude to having to hold the cart in a weird way to move room to room, another wheel bent. We contacted Customer Service. They were helpful on the phone. Said they would send out the pieces needed to replace the bottom tubes that the wheels screw into. They sent me 2 pieces. One for opposite sides of the base rails. I need all 4 pieces to fix the issue. I will try and call again tomorrow, but it would be nice if someone reads this and calls me to confirm the pieces are being sent to us so I can replace the base and make it functional again.
