Deltec Cold Call businesses harassing junior staff into buying products unseen. They use tactics like we have a recorded conversation. Sent us 5ink cartridges with a bill of over $370, to suit a printer that cost $79. Still hounding us even thought the cartridges were returned - actual true cost of the ink is less than $80, go figure. Pushy nasty people. Thet also ring from "unknown' numbers and have no real email address
