Credit Card Issue

I received an e-mail from you yesterday saying you were unable to bill my credit card.  You had already billed it on October 13, next payment not due until November 13.  I checked with my bank and there is no problem with my card.  I did go into Homestead and edit and re-enter the card info. but I would like to know why you sent me that message yesterday since my October payment had been made and has been processed.  I am concerned that this might be an attempted fraud.  Please let me know why this happened and that it has been resolved.  Thank you.
