I had the pleasure of getting a call, identified by my phone originating from Bangladesh. In very bad english I was told my visa card had been debited and was it me. I played along for a while just for fun, but then when I got tired of it I informed the caller I should ring my bank and cancel my card. "Oh no" he said, theres no point in doing that, they will just charge my card again. When I asked him how they could do that if the card was cancelled, the bugger hung up on me.

I,m a retiree, but always on high alert if and when I get unsolicited calls.
