Disgusting service

I placed an order for a Toledo 152cm Plush Base Set on 05 August 2024, and received delivery of my bed on 12 August 2024. The bed that was delivered to me was a firm mattress. I called Sleepmasters on 24 August 2024 to inform them that I had been given the incorrect item. Since then I have been asked for pictures and sent them 3 times. I have still not received any response. I keep calling and every agent I speak to, does not know what is going on.

I called in again this morning and am told that Restonic has decided to reject the return, but they cannot tell me why. How can I be held liable for an item that was incorrectly delivered to me? The level of service I have received from Sleepmasters, Restonic and JD Home services have been nothing short of disgusting. I paid for something, received an incorrect item and am being told they will not take responsibility for the incorrect item that they had delivered to me.
