I might have posted this elsewhere on this forum before.
Many years ago I got cold called from someone claiming to be from the anti fraud team at my credit card company. Told me they were looking into a transaction but before they could talk to me I had to pass some security questions. I told them that they needed to te me something first that would convince me that they were who they said they were. We reached impasse so I said I would hang up and call the number on the back of my card and ask for their anti fraud team.
A few moments later I was talking to the very same person. The transaction they were questioning me about, whilst unusual for me, what one and had done. The person did say that they wished more people were suspicious of calls in the way I had been.
When telephone banking first started I opened an account with a new bank that did it
After a few months they rang and needed to talk to me about something to do with my account
the bloke said he needed to take me through security first
I questioned it and he said they needed to be sure they were talking to the account holder
So I said I needed first to be sure I was talking to someone from the bank
This was ages ago and things were just getting going at the time - but the bloke sounded very surprised and then seemed to suddenly realise that this made sense
I told him I would ring the back back immediately - but he had to make sure that his call was logged on my account or my next step would be to talk to a manager about someone trying to access my account - and then the Police
Like I say - it was a long time ago
but when I rang back there was a note on my account to say he had rung and that it was genuine
I also received an email thanking me for expressing my concern and saying they would be looking at the problem
so - basically - it is all my fault!!!
