Yes, Mark Sadighian definitely has NO integrity whatsoever. He was known as stealing accounts from other sales reps at Nextel. I personally started setting up an account, and he went to this company, claiming he had "more experience" than I had, that the co. should go with him. The co. later called me, after going w/ him as a rep, complaining that he never took care of any customer service concerns, once he got their money. An integrity sales person takes care of their customers and would never steal accounts from other reps - they establish their own. What comes around goes around. Other co-workers also complained he did the same thing with their accounts.
