Who called from 3604439274

Phone only rang once.  Called number back and got a message about some survey being closed.

I got one like this yesterday its a recorded message intended to sound like a genuine call.  " Oh hi this is emily i just dropped my headset"

No message and busy signal  everything it calls

They called, I answered, they hung up after 7 seconds or so.... No sound was heard...

Just for the record,I received a call from this number today. I don't answer unfamiliar callers so don't have any more information
