In the past few years of carrying a mobile, I've tried every major service provider. They all turn out to be the same.
Except my current provider - I haven't got a bill in the past eight months and they don't seem to care much about it either!
However, when I saw this cartoon, I really thought it talks about our gullibility of paying bills that we sometimes don't seem to make any sense of.

I've been through this for many years - and at the moment I just think I'm being lucky :)
