several calls during the day. they ask for my roommate by name but never leave a message. Always get a busy signal when he calls back.

I got several calls while gone too. Don't know who it is, but it's cool that I can google it and find out it's nobody important.

Have received dozens of calls from this number with no one speaking on the other end.  Only once did a person speak, and that was to say he had the wrong number.  He still calls my number though, and it is really making me angry.  Tried to call the number back but only get a busy signal.

i dunno who dis iz

Just checked the caller ID on my land line - I missed about 45 calls from this number in the last 3 days, all during the day while I was at work. I thought my caller ID was broken, but each call is a few minutes apart.
