Comcast incorrectly charged 2,000 customers for exceeding data cap

Comcast's data-usage meter gave thousands of customers inaccurate readings for two months because of a software bug, causing the broadband provider to incorrectly charge about 2,000 users for exceeding their monthly data caps. Comcast has admitted the error and said it is giving refunds and additional credits of $50 each to customers who paid data overage fees that shouldn't have been assessed. Comcast said it's still trying to figure out if the bug is in the meter software, the billing software, or in the interaction between the two. What Comcast knows for certain, the spokesperson said, is that the problem was fixed when it rolled back to the previous version of its billing software.
