Not happy with Seally Bed

I bought a Bed last year October 2024 at Bradlwas. The mattress was dropping in already in just two weeks. The bed was changed and we were tald to rotate the be after each three weeks, apparently that's how seally beds are designed lately to be rotated. That we were tald by the Rep from Seally who came to my house to check the Bed that time last year October. Now it's been a year the Mattress is still dropping inside, even doing the rotation for the entire year. I went back to lay a complain at Bradlaws because that's were I bought the Bed. I was tald I will be called. It's been two weeks now. No call from Seally. I bought that Bed for R7500. I'm not happy at all. Its either they refund me my money I go look for a quality bed somewhere else. Or they must exchange the Bed to a better Bed. I'm not going to let it go until I get assistance The Bed is got two years warranty.
