Who called from 6043317107

they called me very early in the morning 3 times. I heard them breathing once. Not sure who it was. When I tried calling back I kept getting a detailed message stating the due to network difficulties it could not be processed

These imbecils call me at 11 PM on a work week night. Left no message and when I called back, same thing, the recording asks for a passcode.
They are lucky I did not find out who they are.

same scenario.. but 6pm and 3am

same thing happened to me - three times a day.  This is a man voice saying 'Hello'.  After I told him you dailed a wrong #, he said "Okay".

I get a call from this number 4 times a day, I don't pick up but calls everyday.should i go to the police?
