Terrible uncomfortable and noisy sealy queen sized bed. Very disappointed .

Bought a sealy queen sized bed from O.K furnishers about 4 years ago. The bed started being so uncomfortable just after 1 year. The springs are protruding from the side of the mattress. I tried on numerous occasions to contact O.K furnishers as I bought the bed cash from them but unfortunately they broke into my home and stole our safe with all my relevant receipts etc. They have not bothered to assis me in any manner. This is my 3rd sealy bed that I bought but I must say I am very disappointed and annoyed as I paid alot for my bed. And the only reason why I loved sealy is because I suffer from my back and sealy is the only bed that was comfortable for me. However this one is so uncomfortable and makes a hell of a noise. Can someone please advise me on what to do I am so frustrated.
