I have contacted White Castle twice about the fact that the frozen sliders that I purchased have a warning label on them stating that they contain cancer-causing chemicals. Both times they have sent me coupons to purchase more of their cancer-causing food products despite the fact that I have requested a full refund. I have contacted them a third time today. If I do not get a full refund soon, I will be disputing the charge with my bank and reporting White Castle to the Better Business Bureau.
