I got the pop up survey and I didn't know that it was fake.
So I wrote my personal information and $2.5 was paid on my debit card.
I am worried that more money will be paid from the card. What should I do?
Yes, cancel the card SOON, and watch your online transactions ... typical Credit Card fraud process is an automatic test of the card, followed by real-world use of the card. Often they will do multiple smaller physical store transactions in and around your city using "runners" to prevent the fraud detection algorithms kicking in.
