Query: Coating came off and left black powder in food!

After receiving this as a Christmas gift we were, as I assume most people would be, very excited about using our new mixer! After following the "pre-use" instructions in the booklet, and after beginning our cooking process, the metallic coating started to come off the beater, leaving black powder and flecks of the coating in our food! After rendering the food completely inedible, and the beater completely unusable, we called Kitchenaid. The lady on the phone asked me several questions, (such as if I followed the instructions for use in the booklet,) then promptly agreed to send me a coated, white, beater- stating they have had several complaints about the coating coming off the burnished beaters after only a few uses! I, personally, would not buy another burnished beater for my mixer!
