they have also a large operation in Patong/Phuket; the same scheme; you fill out a survey and get a call that you have won and somebody will pick you up whenever you like to receive the price.
they operate in the Holiday Inn and sell timeshares for deluxe suites in Thara Patong. when i was there, they had a lot of first price winners and beside english also german and italian speaking foreigners selling to their countrymen.
they also insisted on closing the deal within my stay in Patong; but as the whole deal was not feasible, i did not sign and did not get my price!
therefore it is a SCAM!
