GreenTech Imaging Won't give you their e-mail address or contact information - BUT want all of yours Los Angeles, California

GreenTech cold called me asking about offices supplies and focused on my printers - they wanted to win my business by sending me free printer cartridges.  When I told him what i pay, which was actually less than what he told me they charge, his math somehow immediately made his cartridges cheaper because they have "more ink" in them.  I asked several times for his contact information, e-mail, he never gave it.  So I quickly googled them and found out that they appear to be a scam.  I told him that Ripoff Report and other links said they were fraudulent.   He quickly hung up the phone on me.   Avoid doing business with these folks.
