My sisters and me paid to Adem in Pamukkale for a private tour, which was more expensive than a group tour. And the next day, they picked us up at the hostel with a group tour of 12 people, with a guide in english and spanish, everything repeated two times. They never returned us the difference of the prices. And also, the worst of all, was that we paid for another separate service (independent the tour) and he never did it, we asked him for our money because he didn't give us the service that we paid for, and he answered that he couldn't return us our money. They work really bad!!!!! It's not a honest company, don't trust on them!!!!
