I got an email on 9/3 telling me that my online bill was ready with an auto pay date of 9/16. The bill includes a $25 charge for a payment return fee due to a problem with auto pay last month. This email doesn't contain any "Do not reply to this email" statement so I replied to it on 9/3 with some questions about the return fee and my reply did not bounce back to me.
Can I expect a reply? If so, when?
