Query: Cheap pan that rusted and warped

I bought a Mirro 10 inch frypan and within a month the pan warped. Its not rusting inside the pan and hard gunk has coated the outside of the pan. I've been using Teflon coated frypans for 30 yrs and never had one made this poorly. I've also never had a fry pan that both warped and rusted; run don't walk from this flypan or any frypan by Mirro
