For example, many years ago, I signed up for a landline phone (when that’s all there was), and signed up for a particular special service that Ameritech was offering that would allow me to have a computer on a modem running 24/7 without getting unreasonable charges. Eventually, I get the first bill and it’s charging me the regular rate. I sigh and call them. They agree it’s their mistake and they’ll fix it to remove the charge and it will be reflected in the next bill. It isn’t. I go around in circles for 6 months, with my bill increasing to thousands of dollars. Finally I call them up and just start screaming at someone, and that is what finally got it fixed.
I’m not proud to have done that, but sometimes it’s the only option. The person I was yelling at wasn’t the one who caused the problem or lied to me, but I didn’t know of any other options at the time. (I was raised by wolves, it turns out.) And, ultimately, it worked.
