This really grinds my gears.
Are companies and the automatons working in call centres really that fkn stupid that they make outbound calls and expect YOU to tell them your full name / DOB / address etc etc, in order to proceed with the call?
Hang on mate, YOU called ME, and I've got no information about you but I'm supposed to hand over critical identifying information anyone could use to impersonate me?
Then if you say, "nah sorry I'm not going to tell you that, as you called me and I don't know who you are", they get all uppity and refuse to continue with the call.
I've had this happen now with a few companies, you would think in this day and age that they wouldn't go around encouraging their customers to spill that information to random unknown callers.
Why don't THEY come up with a way to verify themselves to us?
eg send an email saying "Janet from our call centre will be calling you soon and requesting your DOB and home address"
Or an SMS confirming the enquiry and that someone will be calling you to ask about ticket #5347
Otherwise how the f am I supposed to trust that an unknown or private number calling me and demanding my private info is trustworthy?
I just say that I'm not giving out that info and say goodbye.
