This phone number calls every day.  How can I block it?

I started to receive calls from this number the day after going to light up night in Pittsburgh, they leave no message, call back it either doesn't go thru or you get music like you were on hold.  It is very annoying.

My phone is registering this number on average 5 times a day with no message left. Trying to find a job and hoping its an employer, but no message is ever left from this number

I called this number back twice after they had called me.  each time I got no answer I thenn looked it up on this site and saw that they have done this a lot I have no idea who this was or what they wanted

this number called ask for my family number. called back  busy signal. Don,t know who these people are?

calling several times a day not leaving message

Just answered the number after several calls with no message left. They said "Hi is this Colleen?" I said no and they hung up.

they called 4 times starting at 830am  today so i picked up the 4th time asked who it was and the lady on the phone said her name was AMY and she was calling about a product ordered ....and thats all she said....hmmm

Just called me at 8:30 am ....called back and got ...were sorry your call cant be completed as dialed ...please check the number and call again...

They just called and hung up. It has happened multiple times. I checked their number online and it seems as if it has happened to others too...

This number calls, doesn't leave a message. When you answer the call it is dead air, silence, no one on the other line. I just don't want to be charged for unwanted calls or someone is using it for their benefit. Help.
