Who called from 3178912112

Same thing here. Every time i answer, it hangs up. When i call back, i get a  no longer in service recording.

this number keep on calling me and whenever you answer it goes dead

This is nonsense, the same number keeps calling and I have gotten the same response, hand up and of course not in service when you call back...can we stop this - I have a few more numbers - 214-884-8767, 208-951-7178 & 801-765-6000.

HOW CAN I STOP THIS ONLINE HARASSMENT?  WELL, I'VE JUST GOTTEN A NEW CELLPHONE AND WILL BE USING THAT INSTEAD OF MY HOUSE TELEPHONE. THANKS
