Query: this is fun, but the company wont back it up, or contact me back.

we got this for my daughters 5th b-day instead of rental. it was great for 3 months, than the hand rail of the slide just came loose from the backing and the air goes right thru it and wont hold the air. i tried calling the company, i left email for them, but not a word from them.
