A warnning to all people travelling to Thailland, this agency is very bad, do not deal with them.
they can charge double money with minumum service.
they can change the date of your travel or you transport without informing you.
They misguide the tourist by telling him wrong information about the hotel market.
They pay Tuk-tuk to bring innocent tourist for them, and like this they are still surviving.
They will warn against other travel agency like they are Honest.
They spoil completely your journey and there are some more stories about them:

in General way do not trust a company if you are taken there by a Tuk-tuk.
