I'm curious if you could force them to take cash by paying during a grace period at the beginning of the month. If the month already started then your contract could be setup so that you already owe them all the money for the month. If you owe them money then paying cash is basically _always_ a legal payment option, as in, they cannot refuse your money because it's cash and then say you didn't pay. Make sure to ask for a receipt. This assumes you're in the US though, and you would have do get a kick out of yanking their chain, willing to play the game, etc, but it could be fun/funny.
