I'm getting 3 or 4 a day blank if I call back busy

Just got a call from 479-555-0113 Dir Assist  AR  Answered and would not say anything!  I just hung up !!

Called 3 times within 1 hour. No one on other end.  Called number back and received message saying number not recognized.

Same thing happened to me. He's still calling back to cuss at me - when will the government DO something about these scams!

Got a call at 6:08 p.m. on 4/6/16; unknown 479-555-0113 India accent said he was calling regarding my Microsoft windows on my computer. I told him to lose my number or I would have the FBI research then I hung up. I called the number back and got the recording that the number I have called is not in service . I wish our government could/would do something about this.
