Neil, I know you mean well by sharing this, but if I reported every dodgy scam email I receive, I'd never have time to read ShrimpsVoices!
Seriously, everyone needs to be alert to scammers, who are becoming more sophisticated. No company will ask you to update info in this manner.
Another one to be aware of is telephone scams, where they will phone you on a landline and claim to be your bank. They will ask you "for your protection" to phone the number on the back of your debit card. They then don't hang-up, keeping the line open. You go and get your card and pick the phone up to dial a 'new' number, but you are actually still speaking with the scammer. Their accomplice will then 'take you through security'... you then confidently give them all your security details. If you ever get this, always use a different phone to ring the security number.
