Can you advise on low breast scar & donut lift? (Photo)

I had my breast augmentation late march 2021, and has paid for a full masteoplexy with 400cc hp implants(from 34 A ). As I waited to be taken into the surgery room, my dr made a chage of plans and said he would preform a donut lift. I asked him not to, and he said he would do what’s best. The one scar is very low, nipples larger than before, and he won’t cover the full cost of fixing, and is claiming the donut lift is the same cost. Do I pay for his mishap? This feels unethical.
