Hi guys!
I received the same email, 200USD, 37 seats left and so on.
I personally don't believe them. Someone above said that the SWIFT code was invalid.
It's a generic email not adressed to me but to all of us, strange and not proffesional. The adress of the venue is not exact neither, no check-in time,...
Maybe if you go personally to Merpati HQ you can get a better feedback than paying 200USD to these guys.
Happy landings
