Complaint Review: Ymax Oration

I was contacted at my work over 10 times from a male with a thick foreign accent saying his name was Mark Henry and told my coworker is was an emergency and he needed to speak to me. Then asked them to get my social security number to save my finances. When they handed the phone to me I said may I help you, they shouted my name and hung up. Called again and my coworker asked for his name and number to take a message he began to give her info but kept interrupting and giving her an attitude. He stopped calling after that. I reversed look up the number and it gives me carrier ymax oration Chicago, IL  (312) 450-3802 I Google search ymax oration and I see several scam articles about it. Once I was off work I called the number back. The man with a thick accent answered, I asked who it was, he paused then said Mark Anthony. I let him know that I looked up his company and it was a fraud/scam and that I contacted my attorney and if he contacted my work again we would be filing a harassment lawsuit. He said who are you I told him I refused to tell him and that he better think twice before continuing his scam. He said he was sending the cops on me and hung up.
