AT&T has been fined $60 million by The Federal Trade Commission after they admitted they intentionally slowed down service of customers paying for the company's unlimited data plan.

The FTC says AT&T will be offering partial refunds to customers who signed up for unlimited wireless plans before 2011 according to katc.com.

AT&T has admitted to slowing down speeds to customer's devices so much in fact that according to the FTC "web browsing was almost impossible."

3.5 million customers were affected by the data throttle.

The company now states on their website that it "may slow speeds of unlimited plans after a certain amount of data is used."

If you were affected by this you don't need to file a claim. Current customers will receive a refund in the form of a credit their bill, and former customers will receive a refund check.
