They have upped their game. They now steal your contact list. Happened to my husband. They called his business cell and when he answered he heard a beep and the call was disconnected. Within 15 minutes I got a call, and my daughter and my niece got a call from them. My daughter and I didn't answer but my niece answered and same thing - 'beep' then disconnected. Now her friends are getting calls from this number. I don't answer numbers I don't recognize. My husband has to for his work. Really tired of scammers! Such a nuisance!!
