Query: Unsatisfied

I recently bought this bed rail. We noticed the cover was unraveling a little when we bought it. We washed it once and it completely unraveled. We have had to use duct tape to keep it together. I called and explained this to a customer service representative while asking for a new cover (what most companies would offer because they want to offer quality). The representative was rude--telling me it shouldn't be washed. He was sarcastic when I was inquiring about the straps on the product (as he had me searching for the model number). Once I found the model number he said he can put me on a list to receive a new one but never asked for my information.
