When setting up my printer (MF642C) I must have inadvertently subscribed to some kind of cartridge replacement service. I was just notified that a replacement cartridge had been ordered and my credit card was charged. I tried to use the online CHAT to cancel the order and explain that I didn't request this cartridge and don't have the authority to purchase anything for my company (State of Texas) and was told I can't cancel and would have to send it back. They said I could go on my printer to cancel the subscription, but can't find anything like that. That I could log onto my Canon customer account and cancel there. I can't find anywhere that I've authorized automatic cartridge replacement. Any help would be appreciated.
