I got a text saying they were going to contact me about a potential fraud, from the same number bank has contacted me on before.
Then I got a call from a private number. Probably I shouldn't have answered it.
The person was a bit odd, quite stilted speech, but sometimes they are. He asked me about a DD someone was trying to set up for car finance. Definitely not me. Apparently it flagged because it was in a different area of the country to where I am.
Then he asked me to check my app for any alien transactions. All fine.
Then he asked me to tell him what my balance was because "calls are recorded and this would give them a check if there are any incorrect transactions later". I said "you know what my balance is and I'm not comfortable doing that"...and the line went dead.
I've tried calling the bank but "unusually high call volumes..."
Have I given him anything he can use?. Surely he can't get into the app because I did while he was on the phone? How would knowing my balance have helped him?
