A few months back I bought a HTC Desire from Amazon.co.uk (I’ll post about this soon!).
The size of the transaction was obviously flagged as an unusual spend by NatWest as it triggered a fraud alert. The fraud system is automated and I had to confirm the last 5 transactions made with my card. The computer voice (which said my name in an incredibly bored sounding tone) listed the most recent transactions with suitable vagueness. For example one of transactions could have been something like “£30 at a supermarket in Birmingham” (a Sainsbury’s shop).
The Amazon transaction came up as “£350 at a bookshop in Luxembourg”.
