I had the same thing happen 2 times a recorded message that does not identify themselves or the company they represent. The message is threatening and vague. They sound like it is scammers.
Received a call from 713-454-7998 left a message but did not say who they are or who they are looking for. Stated that I or whoever this message is for to call 320-244-7000 by 11/18/16 or the situation will be out of their hands. I do not answer calls from numbers I do not know and since the message was very cryptic I will not be calling back.
