Will never purchase anything from America's Mattress

We purchased a Serta king mattress from America's Mattress in February 2022. Went to the location where we purchased it to place a warranty claim and was told we need to do it on line. We went home and filed a warranty request as the mattress is sagging, despite rotating it every couple of weeks. I received a reply and was sent documents I needed to fill out and was told there is a $69.00 non- refundable fee to file and for the inspector to come to our home and inspect the mattress to check if the mattress sagged at least 1.5 inches (our mattress sags more than that). I told the rep that this mattress is still brand new and have never of a fee to file a warranty. NEVER EVER WILL I BUY ANYTHING FROM THIS STORE.
