I received a call stating my computer is sending error messages.  I hung up on him.  He called back and asked me why I hung up.  I couldn't understand him.  Heavy Indian accent.  Poor sound quality.   He became very agitated which I thought was comical.  Yes, I actually laughed.  He became more agitated.  I asked who he was.  All he said was he called to help me with my computer.  I disconnected the call once again.  Every time he called back a different number showed up or unavailable.  I have active antivirus and a secure network.  These idiots think they can bully you.  I assure you he called the wrong person.  Consumers beware they are out there and stop at nothing to get your information.  Please be smart about the type of information you give out.  If there's any question as to the validity of the call, call the bank, vendor, etc. directly.
