Who called from 3474336967

these people keep calling me over and over even minutes apart i keep tellling them to put me on a do not call list and they still keep harassing me.

No one there just dead silence

I received a call from this number and it was dead silence

I refuse to answer calls I do not know, but they called 3x this morning and no message

Got a call a minute ago, it was someone telling me I qualified for money that I'd receive in 6 days or something. They knew my name, but I had a hard time hearing them because my phone quality sucks. When I asked them to repeat what they had said the call ended...
