Only to find the 2 pieces of ID were just for them to talk to me and ask for more documents. Rubbish like employment letters (uhhhh, how about YOU call my employer instead of me printing out the “letter” they’ll email me?) or tax return stuff mid-year.
I cut up the credit card and mailed the pieces to their legal department. Someone called me pretty quick and without any authentication hassles.
And how would your employer know the call is legitimate and authorised by you?
I generally say at some point before terminating the call "you should not train your customers to give out account access credentials to strangers" and the caller usually has no clue what I mean. Does no one in the security teams have theory of mind?
This will be the way I bring up the issue with the regulator if I do. I can think of many ways round this issue that would be much safer and not especially arduous.
The chucklefuck that wrote the script that you can get mad at won't pick up your calls.
That's how responsibility works.
