4 months post op, breasts still look the same and one side sticks out. Is the doctor responsible for fixing this?

hi, i recently had a bbl done and fat removal in my arms, back and transfer to my butt and breast, even though I'm happy with my results (4 months) my breast still look the same and there is one side under my left armpit that sticks out a lot more than the other. the question is, is the doctor responsible for fixing this, or do i have to pay again to get this fix? i did pay over 12k for my procedure.
