Had the call from Barclays twice.
Once in HK trying to get £50 out of an ATM, they wanted to know where I was, but didnt say who they were!
Other time I had just paid for lunch in Cornwall and they called up wanting to know how I was also buying gardening equipment in Yorkshire, luckily they managed to stop the scammers by the third transaction in Yorkshire. But you do wonder if I had not paid for lunch on the card if the scammers would have been caught, and one assumes it was not an Indian call centre that knew Cornwall and Yorkshire are hundreds of miles apart
