Who called from 7184801548

The calls are getting annoying, random times . When i pick up the phone the line drops, when i call back it says the number is not in service.

got 3 calls today.  if I answer, no one on other end.  If I miss call and call back, message says # does not exist!

Get a call about 4 times a day. I answer, no reply from the other end, the call drops. So annoying, please stop calling.

I get calls 1-2 times a day and the voice(s) always say, "Let me talk to_______" (saying just my last name totally mispronounced several times). I tell them to take me off their call list and I even registered my number with the National Do Not Call Registry, but they keep calling. Soon I will not be able to even have my cell phone with me on work days.

I received several calls today, I answered then caller hung up.  I  called the same back, response  was "this number is not in service".
