Protect a bed Company advertises warranty for mattress cleaning and or replacement if damaged. Then never intend to cover it Wheeling Illinois

I purchased a temper pedicure bed in March of last year. I have kids so we were more than sold on the protectabed cover with the warranty since the mattress was close to 3,000.00. The sales person showed us a glass with liquid in it and turned the glass over showing us that it could not leak out. The sales person said if ever we got a stain using the cover they would either professionally clean the mattress or replace it, if it could not be cleaned. We put the cover on our bed from day one and never used it without the cover. We removed the cover to wash it ( only ever washing it according to instructions) and saw a couple of spots on our mattress. We contacted protectabed about the stains they sent us another cover and had us send ours in for lab testing. They said the cover was compromised not defective so they would not help. Here's the kicker! We took pictures of the cover before it was shipped with circles of the stains as proof before sending it in. They sent us pictures of the cover cut and said that was why it leaked. It was not cut when we sent it I and we have pictures to prove it. Only thing we can think is they cut the cover when opening the box when it arrived back. I have seen companies like this before that tote a great sounding warranty then do nothing to stand behind their guarantee. Now we have sent them pics of the cover before we sent it back to the and they will not even reply to an email!! Buyer beware!!!!!!
