Apologies all for the issue and the experience that many have described above. Thanks for posting many details here, that was very helpful in having our teams research this issue.
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.
Impacted customers have been identified. We are working to identify customers that may have purchased xFi or unlimited data as a direct result of this error.
