We also need to warn insistently to book a "very special" English and German speaking fraudulent guide / Tuktuk driver and tour shop owner in Siem Reap, Cambodia. He is mostly working in Siem Reap but also offers Tours and bike tours in whole Cambodia. His name is Sok Thon, Thon Sok or sometimes people call him Tom.
We have made worst experiences with Sok Thon.
If you book a guide or Tuktuk driver, check his license, so be sure that he is not this guy. He maybe will not tell you his real name because he knows about his reputation. He is not unknown at the www.
Sok Thon / Thon Sok is a very charming, but absolutely unethically and high intelligent, high professional fraud on a grand scale. He is verifiable active since 2011 and therefore really good. We meanwhile know other persons concerned too. And we are not talking about silly, naive people, but about high intelligent, clever, skeptical and attentive people that he, thanks to his perfection and power of persuasion, could fraud. Even if people ask him about his bad reputation, he tells them, that's the past, he changed his mind. Don't believe any word. The last case we know about is a young women he fraud and cheated cruely at worst just some weeks ago!
So the best thing to do is, to make other travelers aware of him:
Sok Thon / Thon Sok is working as a freelance guide at Siem Reap, but also whole Cambodia and bike tours, etc. and he also drives Tuktuk. He works for several agencies in Cambodia like "travel loops", hotels like the several "motherhome" hotels like "motherhome inn" "motherhome boutique hotel" etc. in Siem Reap and European Travel agencies like "bike adventure tours" and others. He also has a tour shop/bike rental at Oum Khun street in Siem Reap with the name "Thon's tour world" now other people told us.
We are part of a circle of people concerned by him, that found each other by research about Sok Thon after getting fraud. And we would be happy, if other victims take courage to contact us, too. Feel free to contact us by personal message, if you don't like to post your bad experience public. For sure we ensure confidentiality.
