hi i wanted to know who called me as i am expecting one of my uncle and too much desire to talk to him but cant make calls its not going through .he called me march 3 rd from this number and left a voice msg

Guy calls up and said some hackers are trying to get into my windows computer. I was suspicious because of their accent. I asked for their telephone number and name. "302-357-3197, Rodger Black". I ask to identify the computer? He said all my computers had an issue.  He then passed me to his "supervisor" where he stated the same thing and asked if I was in charge of maintenance of the computer? I said "Yes" he asked if I would be paying for the repair. I said "I'm not paying for anything " then he hung up.
