Got the same call asked me for my date of birth , I replied you tell me yours first he said no , before I can continue you must confirm some security details , I said do you really think i am going to give out my personal details over the phone just because your asking me for them , He said yes , I said f*** off and put the phone down . After checking it appears to be be a legit number , But the way they go about their cold calling leaves a little to be desired , Anyway if I get another one I think I will play them along I might tell them I was born in 10AD and my name is Connor Macloud of the clan Macloud and that I am really a highlander and will not die
