Cosmetic surgery

Q: I have a question regarding cosmetic procedures... I know they are not allowed in Islam, however are they allowed when somebody's appearance has changed due to heavy black magic/Jinn? My skin has become very dark on my face, patches of black marks everywhere, hair loss, loss of so much weight due to constantly vomiting (no medical cause) features have become so manly due to this. I'm only 26 years of age but even my teeth are breaking. I've had 5 teeth which have been broken by just chewing normal food in one year (again no medical cause) and its not because i ate too many sweets. I don't want to do this for cosmetic reasons it's just black magic has already destroyed my appearance so much to the extent I'm scared my husband will desire and go to other women. Even me and my husband have sihr of seperation.. my niyat for thinking of cosmetic surgery is just to rectify what has been changed due to the sihr. Not change anything in any other way but just rectify to it's original state. 

Eating from KFC and McDonalds in Muslim countries

Q:

1. Are we allowed to eat meat from food outlets such as KFC, McDonalds and other local outlets in Muslim countries such as Saudi Arabia, Dubai and Turkey?

2. Also, when eating from a local outlet is it ok to trust the individual if he says the food is halal?

3. Also, I have contacted Delphin Hotel in Turkey, Antalya regarding if their meat is halal or not and they replied by saying that they produce their own meat which is cut according to shariah slaughter and I asked for proof and they sent me a video showing how the meat was cut and it seemed legitimate, they also said that if I was to come to the hotel they will show me how the processes in their slaughterhouse, is it permissible to trust them?

Superstitious beliefs with regards to marriage

Q: I got a marriage proposal which I wasn’t sure about so my uncle decided to have hisab done. I didn’t know it was haram then but it came back saying the marriage won’t be good for me and I will ultimately marry someone from another country. I have said yes to the proposal but wondering now if I should believe and listen to what the hisab said? Is hisab real? I am doing istikhara but haven’t had a answer yet.
