This is the second of 4 digit call numbers to my cell phone.

When I answer, no one is on the line.

got call from (4013,4017,4015,4018) n every time same man speaking very bad language.

Someone has just called me on 4011, but no one was there...

I am also getting calls from a number area code 440...Threatened that I have fraudulent not paid a payday loan...and there is a warrent out for my arrest

I received a call form this number(1-4011 actually, but I'm assuming that is the number this page is referring to, in the us the 1 is often left off). I didn't answer because I only answer phone calls if I know the number or am expecting a call from an unknown number.

A voice message was left. It was from my electric company. It was requesting that residents in my area conserve electricity that day to avoid a power outage due to equipment failure.

I live in Pennsylvania
