definitely from the halifax? or did she just mention 'the halifax'?
quite likely a separate company who halifax have sold your details to - could actually have been anyone!
>I still thought it was about banks
you weren't exactly sure who you were taliking to and what the reason was and you were still giving out info over the phone?
next time someone rings you and you haven't asked them to have a think about who they are and what information they are requesting.
do you want insurance? did you ask them to call you?
don't even confirm your name to random callers, and don't give out birthdate, other security information or details about your life.
