The one I never really understood was from a phone company. Whenever thay rang me they asked me for my full name and DOB to confirm my identity. Now, I fully understand that if I ring them.
But they rang me for heavens sake. Who else would I be when they call and immediately ask, "Is that Jim XXXXX ?" and I answer
Yes, it is"
Jim
