Scheduled for a lipo360, breast reduction/lift, athletic definition and chin lipo

I am scheduled for a lipo360, breast reduction/lift, athletic definition and chin lipo. So far I have had the worst consultation experience with his assistant. The price keeps changing and none of my questions are being answered. I was originally quoted ~13000 USD. All of my Colombian friends said it would be less than 5000USD but of course I was charged the US price but in Colombian pesos even though I'm communicating in Spanish. With the exchange rate it's about ~15000 USD. I was initially okay with this price because I was under the impression that the stay, nurse care and meals were included because that is what's advertised on his website. Nope. So another 600USD has to be added to the total. Now his assistant is telling me that I may have loose skin and he may decide to do JPlasma but she cannot give me a ballpark amount for what that'll cost. So I have no idea what I'm walking into. Also I sent a deposit of 4000USD to his US bank but ~500 was reduced from the amount because he withdrew the money in Colombia. What actually makes this experience borderline intolerable is that his assistant won't answer any questions. I have tried to be diligent in planning this surgery and being prepared but she skips any of my questions and just sends me requests for bloodwork, lab results, money, etc. I'm literally talking to a wall. I had high hopes with this doctor because my friend went to him and liked her results but I'm starting to think that the stress from this situation is not worth it. Anyone else experience this doctor?
