This company called claiming to be our copier company. They stated that the cost of our toner was going up and they would sell us a case at the "old" price. They mailed one toner cartridge and invoiced us $587. I thought this was for the case and paid the invoice. A couple of days later they called and said they were getting ready to send out another cartridge and that they would invoice us. That's when I knew something was up. I checked out their business with the BBB and they had an F and all kinds of similar complaints.
