Urban Ladder — Company refused to mobilize the Fabric 3 year warranty

I bought a ADELAIDE sofa from URBAN LADDER, with luxury cloth, which comes with 3 year warranty. The product is under warranty

the foam had manufacturing issue, which also impacted the cloth.
urban ladder stating that they will only fix foam issue, not the fabric.
and to fix fabric they are asking me 54k for whole fabric change,

I am saying just replace the sitting and hand rest part, which is impacted due to manufacturing defect

order no.R[protected]ADELAIDE SOFA SET)
