Sears review: beautyrest mattress

I Purchased a mattress and box springs in 2013. The mattress stated to get deep humps in it, but we thought it might just be a little bump because it was on one side then they began to develop humps on the other side. . I t got worst. We contacted Sears and they to the Sears Mattress Warranty Department ( SMWD). The SMWD sent instructions which included taking the mattress off the bed, take a picture of the foundation, take photos per instruction that included a string and ruler-yikes! We are 71 and 76 respectively and in no condition to be moving a Cal king mattress. Complained- thy said okay just take the picture. The picture wasn't right. I the asked for s store rep to come and take a look... never heard back. The wrote to the President of Sears asking to let us who to contact in the store - no answer. I see some other complaints here that a store rep was sent- not sure why we did not get a rep to come out. All I know is that a $1, 100 mattress should last more than 14 months. I am contacting my credit card company to reverse this charge.
