Who called from 5014909633

receive calls from this number with no one on the other end and a hang up within 30 seconds or so.

Same as John, I answer and no one there.

Someone was on the line but no response. They hung up when I repeated the business name.

Keeps calling when u answer nobody says anything and hangs up

Same as above. Has called me several times and every time I answer there is no one on the line. I mute it and put on speaker to wait and still never hear anything. A few seconds later the call disconnects. I wonder who the source / owner is?
