Bed sagging and no feedback after logging a complaint

I purchased a Restonic Queen bed from OK Furniture. Within six months of purchase, the mattress began sagging badly, and the bed itself started making terrible noises whenever it is used.

I first reported this issue in July 2025 and have been following up since then. Despite sending videos and pictures as requested, I have not received any feedback or assistance to date. This delay is extremely disappointing and has caused great inconvenience, especially considering that Restonic products are known for their quality and durability.
