Call on my mobile: this is John Lewis customer services, please can you confirm your name and address?
Er, no: you rang me - you should be confirming my name and address to prove to me you are who you claim to be.
Call from my bank wanting my name and date of birth before they'd tell me why they wanted to talk to me.
Again: I'm not giving personal info out in response to an unsolicited call
In both cases (this week) I told the caller that unfortunately I couldn't take the call as I wasn't willing to give my personal details out without proof of who I was talking to. The chap from John Lewis seemed to think this was preposterous, yet he told me he couldn't tell me what he was calling about until he confirmed my identity!
AIBU here or is it flipping cheeky for companies to expect people to divulge details on the phone when cold called?
