Phone companies are notorious for stretching the truth...Centurytel is no exception.
Most of the time, lies aren't this obvious. Most of the time they're buried in ad copy, subtle tag lines or internal memos.
Unfortunately, bad times seem to bring out the overpromisers in droves. Please don't allow yourself to fall in this trap. Make the best out of what you've got. And, try to improve upon that every day.
