Our billing system was out-of-date. It is now resuming normal operations. All customers who asked for down time credit by September end should have received it, and you should have received an explicit response to your email or trouble-ticket request confirming this. (If you didn't, please let us know, in the form of a reply or follow-up to your original request for credit.)
Unfortunately, you may see multiple invoices and/or credit card charges close together in time. All credit card charges should match your online invoices, which you can view within the billing system. This way you can easily verify that you have not been overcharged.
Thank-you for your patience during the time that our billing was backlogged.
