"What is your phone number on file?" Shoot, I don't know, it was an old number that I changed maybe 6 years ago...
"What is your address on file?" I've moved maybe five times since then? I tried "was it in another state?" to narrow it down, but the answer was "I can't say that".
"Okay, we can verify you by classes you took..." Great, now we're getting somewhere! I took Intro to Ethics. "We need to know what term." Okay, this is tricky, it was like 10 years ago... Fall of 2006? "We need to know professor's name." Um. I think I have the book here, I know he wrote it... Professor McLaughlin? "I also need to know the day of the week the class was held and what time the class was."
Are you effing kidding me? I wish I was joking. I ended up just calling my old advisor and he "verified" me with an email to the helpdesk.
The rep on the phone kept prompting me when I was unsure. She'd mention an amount, then when I was unsure they'd say something like, "maybe it's for your mortgage...? Maybe the company begins with the letter 'N'?"
It was all a bit silly, security theater at its finest.
