Base unstable after two weeks

I bought a Restonic bed about ten years ago and was very impressed with the quality of the product , so when it was time for a new bed I did not even look at another make and bought a Restonic again at Sleepmaster in Potchefstroom. Mistake. The bed was wobbly from the start , the base has loose planks and there is a knocking sound in the base , something is definitely loose inside. I reported the problem to the JD group but it`s about a week now and nothing has been done since. Not impressed
