Had Chin Slide 2 Years Ago but Doctor Didn't do Fat Transfer to the Chin we'd Discussed, Why Would that be?

I had a chin slide 2 years ago due to the dent in my chin right under my lip. Now I want to have fat transferred to the dent because as I age the dent seems to get deeper. All my life I've had a dent and wanted it removed that's why I had the chin slide. The dr was suppose to do a fat transfer but didn't.
