How Do I Ask for Free Revision Surgery?

I recently had an earlobe reduction, and there is absolutely NO noticeable difference in the size. The only change is that my earlobe is now attached to the side of my head. When I went in for my consult, the doctor and I both agreed that leaving my ear unattached rather than attached to the side of my head would look better. He even stated that in his opinion unattached looks better! I'm not a very confrontational person by nature, so I want some advice on how to ask for a free revision.
