Amazon.co.za kings gas stove - DO NOT BUY

Bought a Kings gas stove through amazon. Bought it mod December and noticed by end of February that it is rusting badly. I followed the care instructions to a tea and even reviewed it as bad but no contact from amazon. The return policy was only till January. How can a gas stove rust in 2 months? It says I have a one year warranty but I can't get hold of anyone!!!
