An anonymous reader quotes a report from Ars Technica: 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 told Ars it is giving refunds and additional credits of $50 each to customers who paid data overage fees that shouldn't have been assessed. Comcast engineers found that the problem began after the company started rolling out a new billing system in early August. The data meter was apparently still collecting accurate data, but the numbers were being reported in the new billing system incorrectly. 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 on October 2. Comcast's statement to Ars said: "While updating our data usage meter to a new system, a software error occurred resulting in a small number of our customers being billed incorrectly. We're very sorry for inconveniencing our customers and here's what we're doing to address it: We fixed the technical issue, we're proactively crediting the accounts affected, and we're giving those customers an additional $50 credit to make it right."
