Hello crj,
Welcome to our community and thank you for reaching out to us here. I was able to locate your account and review the billing information. As GabeU mentions, the bank account or card on file on your account will be charged the date your bill is generated, with the final day to pay before alerts begin appearing over the service regarding the billing status occurring 10 days from the issue date.
I do see that our agents were able to provide you with the credit for the modem and a refund for the overdraft charges. Please let me know if there is anything else that we can assist with or if you have any other questions.
Thank you,
Amanda
