SEALY HORRIBLE MATTRESS QUALITY

I purchased a bed in 2023 and in less than a year I can feel the springs in the bed , the bed has dents all over and the base of the bed has fallen through . I have been trying to have it replaced since last year September and after them finally getting through to me now they say they cannot replace the bed because it has stains on ? Seriously ? I know its under the warranty but are you taking away the fact that i paid R7000 for a bed to have this horrible quality and be done for within a year and all you worried about is stains ! How is that a deal breaker ? I AM SO MAD
