Sure ... I can do that, but doing it once a month until the end of time isn't going to look good. :)

There's presently no place in FileSonic's account settings to update your billing info, either. I don't know if there might've been before; I've had the account for over a year but never needed to change anything until now.

For the last hour, I've been trying to cancel my FileSonic premium account, which is set to rebill me in a week's time. It is now apparently impossible to do so. Upon filling out the cancellation form with the correct info and clicking "Cancel," all one is presented with is a screen titled "AN ERROR OCCURRED" and the helpful message "application error." One might suspect they've intentionally disabled their cancellation mechanism to stop the mass exodus of users (and therefore money).
