I keep getting calls from this number about 3-5 times a day at all hours on my cell phone. I do not answer the calls for I do not recognize the number. This is becoming very annoying.

You have to call the number 773-481-2995 Northwest Bus back to get off their list.

So creepy i keep getting that call too. but i finally answered and no one picked up . wats up with that?

It's actually an automated dialing service that continuously dials your phone number until you pick up.  That's why, for those who did pick up, there was a pause before a live person got on the phone.  I received a phone call from a service that 'specializes' (I use that term loosely) in college placement.  Basically they ask you what what career you're trying to persue and they forward your information to relevant schools.  Unfortunately, the next day I received so many phone calls it was crazy.  It's this number that keeps calling me though.  

By the way, I have you all beat!  This number called me seven times today, eight times yesterday, and five times on Saturday.  Does anyone know how I can block this number without having to sit on the phone with the caller for 30 minutes listening to his sales pitch?  This is borderline harrassment at this point!

OMG i cant believe this. i just randomly decided to type the number that kept calling me into google and this was the first link. thanks for the heads up guys.  they called me 3 times today
