Out of high school I've worked a couple of years for A1 telecom(in Croatia) in customer service. When someone called, all I was required to ask is their OIB(Personal identification number) and they could literally ask me for anything if it's a residential user.

Want to cancel 20 numbers that still got 2 years until the contracts expire? Sure, let me do that for you. Want to change sim? Sure, just give me the new sim number. Want to add 5 tariffs to your plan? Sure, do you want phones with that?

That was 6 years ago but I still got friends I talk to there, and not much has changed.
