No results after Brazilian butt lift.

I have had my BBL done five weeks ago. I've waited patiently before making any conclusions. My butt is as flat as it was before the surgery. It was bigger right after the surgery but now I know it was just the swelling . My question is what can I expect from my doctor? Obviously I would not do a revision with the same doctor. Can I ask for a partial refund? What would you tell your patient if you yourself did not see any results after the surgery ? Thank you
