Robo-call saying my Visa debit card was suspended due to suspicious activity or something like that. Wanted me to enter my 16 digit card number. I put in 16 random digits - seems it at least does some kind of validation. Rejected my fake number. No institution named.
I was on the other line so did not answer. No voicemail, so called back, but just rang and rang and finally cut off. Scammers, all. May they rot in Hell.
