Poor service

Good day, I need your help. I bought a edblo queen bed at sleepmasters wonderpark 1st week of February 2025, R6000 cash. From March the mattress went down already within 2 months, when I call them they said I must wait for 3 months to complain or rotate the mattress. I mean I didn't buy the bed to rotate each and every week. I'm not happy at all. They always give me references whenever I call but no help until now. Portia mchayi. I'd number :*** Contact :***
