Who called from 7047693513

I received a call from this number yesterday and today.  When I pick up I can tell there's someone there, but then they just hang up.

This number keeps calling but never leaves a message.  I don't answer if I don't know who is calling.

Very annoying..does not speak.

Received a call from this number with a+ prefix. I did not answer. Does anyone know if this is a scam? I don't answer calls from numbers i don't recognize but sometimes i use an in ear Bluetooth headset that answer calls automatically and I'm concerned that i could get scammed by calls like this.

Insufficient information
However, if you tell us what the caller said, we will not have to unpack an Ouija board to try and get an answer.
