I purchased a Kingsdown King size mattress and boxspring.

When I received the mattress and opened it up there was a slice on the side of the mattress
When I made the agreement to purchase the mattress I was informed that it was in perfect condition, and that it was a returned mattress from someone who could not fit it in their place. At no point in time was I told that there was a slice in the side of the mattress. I was informed that if there was a problem with the mattress when I received it I would have 10 days to contact dormez-vous. When the delivery people brought the mattress I was told that signing their form was for receiving the mattress and that if their was a problem I would have to contact customer service. I contacted the salesman Danny Matta, about the problem the day after I received the mattress, Danny informed me that he would send an email to the customer service and that someone would call me within 72 hours. No one contacted me so I called the store, and I Danny again told me that he would send another email. Still no contact, I called again, and someone else at the store, didn't catch the name, told me they would send yet another email. Again no contact, I went to the store and the man that was there told me that he was the one that sent the most recent email and he would send another. Still nothing, I went to the store again today, and a young lady named Dimitra Diamantakis told me that ripped mattresses do not have warranty, and that someone should have contacted me already about it and that she would send another email.
Finally someone contacted me from customer service and informed me that I had accepted the mattress in good condition, and that I had never contacted anyone previously about the mattress, and that they were not willing to do anything.
I never would have agreed to purchase a ripped mattress.

*EDIT*
I just got off the phone with Steve Gunn, The CEO of Sleep Country Canada/Dormez-Vous, he said he will look into it and then have someone call me back.
It took 19 minutes after speaking with Mr. Gunn, for someone to call me and make a delivery date to exchange the mattress for a new one.
