Centurylink is a giant, scammy telco notorious for larding its customers' bills with fraudulent charges, and instructing its customer service reps to do everything possible not to waive those charges; they also open fake accounts in their customers' names, a la Wells Fargo, and then rack up charges against them.
Naturally, they're getting sued; their customers have banded together in a class action suit. Centurylink has a great defense for this: it claims that these poor saps don't actually do business with Centurylink, they do business with a bunch of shell company subsidiaries that no one has ever heard of. According to Centurylink, it has zero customers.
