I used to work in CS for a cell phone provider. The most memorable call I had from that experience was a woman who spent over an hour yelling at me because her daughter had ordered a $1200 phone upgrade without permission. She was absolutely sure that it was illegal for us to charge her for that, because her daughter was not authorized to use her card, and because her daughter was under 18.
She didn’t want to return the phone, because she didn’t want her daughter to hate her. She just didn’t want us to charge her for it.
