Supply World is a terrrible phone scam. They called saying that they were our company that supplies our toner (which we do have a company that supplies our toner, just not them) and placed the person on the phone's name on the shipping label. We did not pay the invoice and I received a flood of faxes and letters wanting me to pay the $700+ bill for one toner cartridge. What a scam!!! I told them that they could either send a prepaid UPS form or pick up the toner in person where I would have a police office waiting for them. Guess which option they chose? BTW, if you call their 877 number is goes to a macine but if you call 877-845-8072 you will get "Customer Service" which consists of one person named Annie.
