What can be done if I am not happy with my Brazilian Butt Lift results? Will I have to pay for a revision? (Photo)

I had a Brazilian butt lift done 2 1/2 months ago and fee like the results look square and am losing all the fat injected. I was told that I got 1500 cc in each cheek and with that I was expecting amazing results with that amount but I very depressed about the outcome, shape and size. Would I be expected to pay for a revision?
