Sleepless nights due to Restonic Bali bed

I’ve purchased Restonic Bali around Feb/March my bed is sinking . Restonic manufacture head office asked that I take picture's of the bed and they said the bed isn’t sinking. The bed is sinking to a point if one is lying down on top of the bed you won’t see an object lying next to you. I’ve logged a call In November till to date my query isn’t resolved . I’ve asked store manager Selalelo to get regional manager to contact me and I’m being told that he is in meetings and he never bothered to call me nor respond to my emails. May I request the store or franchise owner to call me in this regards. This bed is sinking like Titanic and I was told that the guarantee is 9 year and it’s only 9 months down the line sleeping 🛌 on Restonic Bali waking up back pains. I have a chronic of Endometriosis that also results to back pains and now my medical condition it’s worse due to uncomfortable 🥴 sleeping 😴. I’ve brought my medical condition to the store manager asking if they will take accountability to my physiothe****** ills and she is not optimistic to accept liability my medical bills. The night is long whereas one should resting instead one stays up no peaceful sleep on Restonic Bali.
