I got a call the other day from my bank (Nationwide).
The caller asked for various personal details and would not even remotely indicate the reason for the call.
I refused to give them, obviously.
He would not even say which bit of the bank he was from (current a/c or visa etc). So I had no idea if it was about some less than important matter, or a query re a transaction which if not resolved would leave me with a useless (blocked) visa card.
(I wonder how many people would have given their personal details at that point - a lot).
So he said "call us back on such and such #".
The # was actually on my visa card so I called them back.
Some time later I got through to somebody, and it was indeed an irrelevant call about some piece of relative trivia.
But let's say this happened abroad. The call would have been very expensive, but if not made, and it *was* about a CC transaction, your credit card becomes useless.
Why these stupid people cannot ask a few "security" questions which are good enough for the job?
I ditched an MBNA card because they did this (query some transaction) on about 50% of my holidays (luckily I always had a fallback card). Oddly enough they did not query any holiday transactions; they queried mail order ones which in my case were pretty regular and which just happened to go in while I was away.
What I also can't understand is why they cannot employ some people with a *brain* and answer obviously trivial questions either with an open phone call, or by email.
