Kenwood airfyer 7L

I bought a Kenwood airfyer 7L from hi fi corporation in Centurion but within six months the so called non sticker pot was peeling off and rust was exposed. I tried to take it back at hi fi corporation at Wonderpark mall but they told me they can't help me because it was not covered under warranty so now iam stuck with something that iam not happy 🥵🥵🥵
