I love cell phones dont get me wrong but i hate cell phne companies who have what is known for cell service bullying.There the ones that call you over and over after you have politely told them to stop.I found a way to combat them.Confuse them and dont add any features.When I get repeated calls I know they are not fully traine so I annoy them back by asking tech qustions i know they cannot answer and when I stump them up on something and thei tongue tied I tell them why I want add the service.I eman why should I add a servie they dont even know how to use?They dont know what to say and usually give up.This works for all telemarketers.I love them.I use to hate them until I took a job as one,one time and learn the trade and most telemarketers have minimum knowledge about what they are talking about and are reading a script so when you ask them to many questions then they hang up and dont call back.I also add them to the Donot call list.Cell phone service bullies are the worst.Who hates them?
