Brah, it happen to me before. You must be awful at talking to people. Grab any janitor, bring him to the ATM and mimic what happened to your card. There is a number you have to call and they will come retrieve your card.
You paid a bribe as insurance. Not saying that it's fake but the amount of profit they make out of this insurance is insane. You are not supposed to open a bank account with nothing but a passport. Usually, your rental contract is enough.
Or you will see people like Michael who also got con, who can't accept what happened to them and try to denied that they paid for something they didn't have to.
The 5.9k baht fee is a common scam, you do not need to pay anything to open a bank account while on visa exempt, especially in a touristic city like Pattaya. One thing that most newcomers don't know is that Bank, Hospital, etc, will sometimes try to pull stuff like this if they perceive you as naive (new). You seem unwilling to listen to people who have posted so far that have been here for 10-20-30 years, so I won't even try to convince you that you are wrong. All I can say is... you will probably get scam again in another context. People like you tend to never learn due to their ego getting in the way.
