Just as a point of clarification to Stephen's comments, yes we certainly did remove his site, but only after we had verified that the site was operational on Mindraven's servers.
It is company policy to remove a cancelled account immediately upon cancellation unless directed otherwise. We apologize for the miscommunication on this.
As for the billing error, yep, we certainly did send Stephen an invoice on January 28th. We failed to remove his account from the billing system before the next billing cycle. Stephen notified us of the error, and we corrected it immediately and again, apologized for the error.
