Had gynecomastia surgery but no gland removal?

At consult doc said he'd do gland excision and vaser lypo. Got a sono pre-surgery and the nurse said the gland was small/no-gyno. I mentioned this to the doc but he said there was real gyno via feeling around.. After the surgery the doc said he only needed to do the vaser (no nipple incision/gland removal). Also didn't need the drains. Since the scope of the surgery was much less than anticipated, do I ask for a partial refund? I know the result is most important but it was not cheap (7.5k).
