Poor workmanship

I got a restonic bed from Russells on 3rd December. The bed was making noise as if I'm the second user. My whole body was sore the next day. on top of that have back problem. On the 5th December I went to report, but they didn't seem interested. One of the consultants said I should give it time. I'm not sure time for what. Please assist on how to resolve the issue.
