Who called from the number +1 (619) 745-4863

They called me from this number, but said nothing. After several attempts to get whoever’s on the other ends attention. (Which somebody was clearly there on the other end) I was forced to end the call and hang up. I then decided to return the call just in case it was a bad signal or something so I called said number in question back, and It was immediately terminated after one ring. I then proceeded to call said number back two more times. For a total of three calls to the same avail. After the third time a automated response came on and said to me that I had tried to call the number to may times and that it would not allow me to call it back again. The message said the maximum number of calls exceed goodbye. I don’t know who or what this number is. Or what they want. Or even how they got my number. All I know is that it definitely doesn’t seem safe and I wanted to leave my experience to maybe help some one else
