I have a credit card on autopay. I know from history that if the due date is on a wkend, the funds come out of my account the following Monday. The credit card rep told me that their system, however, inquires about whether funds are available to pay on the due date and if they aren't, the request is rejected and I am charged for failure to pay. Is this the way things really work.......their system talks to the payer system during the wkend and determines if funds are available at the moment? Or do they talk on the next business day......in this case after Labor Day Monday?
