Called and left no message.

Received call two days in a row. 1st day no message left. 2nd day, I answered to call, no response from caller, immediately disconnected. Called back right a way, and got recording stating the number was disconnected. Call seems to be computer generated. Don't answer

Just got a call from this number. Rang twice, did not answer. No message.  Do not answer any numbers I do not know!!  Wasting their time HA HA..

Called two days ago and then today.  Only number shows up on caller ID. My machine picks up and I hear a couple computer sounds and then call disconnects.
