Understand BG but there is no way I would give my date of birth and particulars over the phone to someone who has called me. It may be a companies policy but its also my policy and right to not tell a complete stranger on the phone those details.

This is only because ive seen the damage a scammer has done doing this. Yep...a friend of mine gave her details over the phone only to have the person on the other end not be who they said and book up $10,000 of items in her name. Her name was mud for a long time credit wise...so no I wont give me personal details, no matter who it is over the phone if they ring me. We have the right to some privacy and to protect ourselves
