Who called from 3019693002

They been calling me all day

they keep calling and won't leave message...have no idea who it is

Been getting calls from them for the past two weeks. Don't recognize the number and they don't leave a message.

i have recieved 4 calls today by this number... idk who it is

Got a call from this number and tried to call it back...hangs up immediately.  Got a call from a like number, called it back and they asked if I wanted to add my number to a do not call list and I did.  Hope I did not add my number to some list that will now will be sold ot more annoying callers.
