No consistency in their treatment of customers

I purchased a Rest Assured Weightmaster Bed on 28 November 2022. It was delivered after 14h00 on 30 November 2022. I complained on 20 September that the bed was sinking after 9 months and is making a creaking sound. It is really uncomfortable and that should NOT be the case after 9 months. Graham Vorster inspected the bed on 28 September and issued a report on 3 October 2022 stating that there’s no problem with the bed. This bed has a 2 year guarantee and a 20 year warranty. Furthermore, I spoke to a neighbour yesterday and she told me that she had 3 Rest Assured beds replace yesterday due to it’s sagging after a couple of months. There seems to be no consistency in their treatment of customers. I will never buy a Rest Assured bed again and I certainly hope others learn from my unfortunate experience and never purchase from Rest Assured. What a Joke this company is???????????????
