Had a call supposedly from my bank asking me to confirm a recent card transaction which they say has been blocked.I had made a payment but checked via my banking app and the payment has not been blocked so this clearly looks like a scam.

Called repeatedly by an automated system claiming to be Fraud prevention after my bank stopped an unauthorised payment. Hung up and called my bank who confirmed my card was being misused and this number is probably the scammer trying to get my card unlocked!

Says they are Bank of Scot trying to verify if a payment they declined for me was legitimate, but on the app it says there have not been any payments declined, so definitely a scam.

They leaft a message which started ‘hello, this is the fraud department.’ Any genuine call would announce the name of the company. Red flag.
