Botched cheek liposuction. How do I fix this? (Photos)

I wanted buccal fat removal, and the doctor talked me into additional cheek lipo. He removed almost a full syringe of fat from each cheek. Now I have big dents in my face and there's fullness under my chin. I look much worse than before. The doctor says he can fix it with fat grafting and a neck lift with salivary gland reduction. It's a risky surgery, and I am worried. I don't know if I trust him at this point, and it's a lot of money. What do I do?
