I keep getting constant, back to back, calls from this number in the middle of the night - usually one minute after the next between 3am and 4am. The first time I got this call, I picked up and it sounded like a pocket dial. I ignored the next three calls. I picked up the fourth and heard this creepy voice say hello, where I responded by yelling to stop calling me. The next night I received 7 more missed calls between 2:30am and 4am. I have no idea who this person is and it is making me feel unsafe.

I have te same problem, I've called back and their voicemail is a real man, not an automated message.  I have threatened to call the police if he calls back, but he still about every other night
