I have had Centurylink for 3 years. I've paid $30/month for 50mb speed. I've been happy.
Today I visited my father to learn that he switched from Cox to CenturyLink. My father is old and has a brain injury in which he doesn't think well for himself. Apparently, CenturyLink set him up with a system that would power a shopping mall, and he was told that is what is necessary. He is paying ridiculous amounts of money to them for services that aren't necessary or being utilized.
