- I call the bank and ask them to block the card and access to the account
- I do not send any further BLIK codes or text-message codes
- I change the bank password and the email password from a phone or a computer that did not open that link
- On Facebook I log out other devices, change the password, and turn on an extra login check
- I report the ad on OLX or Marketplace and I stop the WhatsApp chat
- At the police I give the time, the amount, and what was typed or read out
Before a code goes out: a friend on Facebook, a payment link.
