One of the methods employees allegedly used is tacking on up to three accounts to a single customer's phone number -- including those who just signed up for a free trial -- and running their credit card three times. In some cases, customers were reportedly charged for a subscription even though they made it clear that they didn't want it. Sales employees allegedly made and used fake email accounts in both instances.

Customers were sometimes charged for a DirectTV Now subscription but were told that they were being charged for another thing. There were reportedly even times when customers were told that DirecTV Now was part of a package when they were actually charged an extra monthly fee.

The investors involved in the lawsuit called the service's "apparent success" a "complete mirage." They said the "information provided by multiple former employees of AT&T and its affiliates from across the country collectively confirm a wide-ranging fraud, perpetrated at the highest levels of the company." As for AT&T, the company told Bloomberg and later confirmed to Engadget that it plans "to fight these baseless claims in court." We also reached out to the carrier for more details and will update this post when we hear back.
