Failed hair transplant - booking new at Heva

Had a failed hair transplant at Esthetic hair Istanbul a couple of years ago, and I'm now booking a new one at Heva very soon. What should I be aware of beforehand?

They quoted me 3000 grafts, and I have to buy the the gold package for Dr. Seda.

I especially want to focus on the front and middle. I also want to just adjust my hairline a bit (especially in the right side), but not lowered because of the density might not be as good.
