To the OP, be proud that you’re brave enough to share this. I live in one of the 3 countries bordering Cambodia, and yes I have been called by scammers and managed to ignore them every single time. A political solution is a must if the world even intends to solve this growing pain, with the end of Cambodia as a country a good solution. Until then, be vigilant and advise others to be as well, and keep pillaging Cambodia whenever an opportunity arises. I always refer to them as Scambodia in daily conversations, gaining popularity myself for that.
