Caller asked for the name of our receptionist and mailed a box of pens to our office. The invoices stated 216 pens at a price of $0.69 each times two boxes for a total invoice of $318.95. Got a call from "Robert" seeking to collect payment. Told him that we sent the unopened box back Global Express. He breaded me on the phone telling me he was going to send me to collections. I told him that he was and never will be one of our vendors, that he and I both know this is a scam and I told him to cease and desist. I then hung up on him.
