Care to elaborate? I hadn’t known they were evil.
Look up "Phone Cramming", it's when you get mysterious charges on your phone bill for services you didn't order.
Verizon and their partner ILD Teleservices are notorious for it.
Sure Verizon will claim* they will remove these charges if they happen, but good luck with that.
* Their trick is to tell you to pay your phone bill in full with the phony charges and they will credit you next month, but when next month comes of course there's no credit. Being that trying to get in touch with their customer service can take a hour or more, they are hoping you just give up and pay the bill.
I am thankfully Verizon free now. I will go back to using a rotary phone before I ever use them again.
