I switched fro COX phone service to CenturyLink when I moved. BIG MISTAKE! Turns out "unlimited long distance" service they offer is not really "unlimited" at all. Cannot use it to dial conference numbers - never explained that to me when I signed up for it. Cox does not have this restriction. So I changed my service to a thousand minute a month plan for an extra $29/month, but a bundle including voice mail, caller ID, and other services was not available with that plan so my total cost basically doubled from what I was originally quoted - BIG SCAM! To make matters worse, they didn't process that order correctly anyway and they suddenly cut off all long distance capability. After two days, I'm still trying to get my long distance service turned back on - no one, literally no one there seems to be able to fix the problem although at least three people in customer service, repair, and the "fraud detection" department have all told me it's fixed. Guess what, it's NOT!! It isn't the long distance problem that's so aggravating, although that's pretty bad, it's the completely inept customer service. I research and write about technical support for a technical support association - this is one of the worst examples of customer service I have witnessed.
DON'T USE CENTURYLINK FOR TELEPHONE SERVICE - USE ANY OTHER ALTERNATIVE.
