They called two times today. I did not answer any and they did not leave any voice message. As I am in a job search, these annoying calls must be likely from career advisor or back to university places but not from any serious work offer. As far as I know, it is illegal to collect phone numbers to use them for any different purpose as these guys are doing.
Received a call today using the new scam which has been reported in the news, in which the called asks "CAN YOU HEAR ME OKAY?" in an attempt to get the victim to say "YES" so this recording can then be used as voice authorization for fraudulent charges! DO NOT ANSWER THIS CALL, OR IF YOU DO, BE SURE NOT TO SAY THE WORD YES!
