TTK Prestige — Prestige non-stick pan

I had bought two prestige non-stick pans as on 20.02.2020 (two years warranty) and on 27.12.2020 (one year warranty)
Both these pans have given a horrible experience neither
Foods get stuck on the pans after sometime in use.
Both shop owners are replacing the pan inspite of having product under warranty
Going a Prestige as a brand name I feel cheated as the product are not at of any use.
