You should never, ever, reply to emails from your bank. because your bank will never, ever email you. Any email claiming to be from your bank, isn't. It's from a scammer.
Barclaycard epdq sent me an email asking me to confirm my email address. And it looked very realistic, so I looked at it really carefully. And it still looked realistic. And how would a scammer know I was using Barclaycard epdq? Well, how does a scammer know I bank with Icky-scratchy Bank - they don't, they just send out a million emails, and some of their targets really do bank with Icky-scratchy Bank. And I don't.
So I called tech support there. And they confirmed that they really had sent me an email asking this. Stupid, stupid, stupid.
So I gave them a *long* lecture about how no-one with any sense will reply to their email, and did they really want people to reply to emails apparently from the bank? And I asked for my complaint to be escalated.
Why do I have to keep explaining to banks about computer security?
