Sealy Anzio Bed matrass

I bought a Sealy Anzio Firm mattrass first week of December 2024 in Port Elizabeth 2days later the mattrass is sagging reported it in store took pictures still no response I'm soo disappointed I have to continue asking for feedback on the matter seemingly I'm going to spend Christmas with a sagging bed instead of a new and comfortable bed.
