Hi. Although it may be too late for you, I'm sure that others may be reading this as well. This all sounds very fishy - it appears that either they did not know how to accurately assess things at the beginning, which would call their competence into question, or they purposely under-assess things which would call their ethics into question. Either way, this story is troublesome.
The best thing to do in this case is to get a second and third opinion. It may be that you will need to travel a bit - there may be "problems" in your region as far as finding good and honest practitioners and it may be worth expanding the circle within which you'd travel to find the very best plastic surgeon.
