only let it ring 3 times then hung up??? has happened I think before but I have never written down the number...I will keep track now.

An automated call looking for part time people.  Didn't go through with it and just let it time out while writing down the number and searching for it.  Probably some kind of scam.

Called today about 6:03pm. Didn't pickup, went through answering machine. They did not leave a message.

also got three calls in one evening with no messages

Have received 2 calls in the last 2 weeks from this number on my cell phone but keep missing it. No message

Got 3 calls at home and one at work, after reading the above comments I'm suspicious.
