Kurl-On — Sagging in mattress

Address: 560076

Hi i bought a kurlon king size classic mattress thinking that i am spending money on a trustworthy brand, it was bought in 2010, already since one year we are facing severe back pain due to sagging, i raised a complaint with customer support. The guys came and said there is 1inch sagging and nothing can be done as it is not 1.5 inch and beyond 5 years. Is this the kind of support you give? I feel i have wasted my hard earned money on you guys. I don’t have a proper resolution yet on my ticket 1447941. Can someone please look into it. Else for sure i will escalate this and share with everyone i know in my circle.
