I am interested if anyone knows
The movie were the kidnap people
Lose their hearts for sale on the black market ?
I think the film was shot in the eighties or nineties !

Probably not the film you're looking for (much more recent than 80s/90s) but Paradise Lost has that premise. Also, Urban Legends: Final Cut has a bit like that at the beginning.

How about...

The Harvest (1992) - IMDb (http://uk.imdb.com/title/tt0107084/)

"Thanks again for your reply but that's not what I'm looking for !"

I think that in the film were 2 sisters or friends...
And they take their hearts and some parts of the body...
I'll try to remember some more details but long ago I watched that movie...

Ok, this is my last guess

Dirty Pretty Things (2002) - IMDb (http://uk.imdb.com/title/tt0301199/)

If not, hopefully someone else can help.
