RESTONIC BED A SINKING BOAT!!!

I bought a new restonic bed on the 1st of July 2022, we slept on it only one night and in the morning when we wake up, the family bed is no longer flat, it went down showing where each person was sleeping. As I speak now, this is no longer a bed but a boat, this is very much painful, I took pictures and called Russells Birch Acres which is where we bought the restonic bed from, they took pictures to restonic but instead of helping us they told us to take proper pictures and told me that they will never help me. I told them that I want my money back cos I can't use this boat as a bed. Imagine we go to work and come home tired, hoping to rest on the bed that we didn't even buy on credit but paid cash for, but instead we wake up with painful ribs cos every time we sleeping, we just sink in it😭😭😭as am writing this now, my body is painful cos of this bed, we spent the whole month of July with painful bodies, we even think that maybe we need a massage but it would not help cos we will come back to sink in this so called Restonic bed😭😭😭 what hurts me most is that the two ladies from Restonic Briget and Maletsatsi they don't have a good customer service and they kept on lying to the Russells manager that i don't pick up my phone and they are very rude, they told me that I am unfortune that they can't help me, and won't get exchange nor my cash back 😭😭😭😭
