There was a transaction I needed to cancel but the company were refusing so I needed to phone my bank. I forgot the banks number is printed on the actual bank card, I did a quick google search for the number but must have phoned the wrong one. The hold music was the same and they sounded just like my bank. They needed my login details because of their new security checks. When they told me they were inside of my account I panicked, realised what I’d done and found the actual number. The woman on the other end also helped and assured me that my account was safe and helped with the transaction but asked if I was referring to an account with a balance of less than a pound (but she specifically said how much) and I could’ve sworn I heard her sniggering and trying not to laugh. It’s not that I didn’t have any money but I had moved my balance into separate accounts to keep track that could all be accessed by the login details I gave to the scammer.
