I have been recieving a call form this phone number at least once a day as well as my roommate. When either of us call back it give us a fax line sound or it says the phone number is invalid. How is it invalid if it just called?

lower my interest rate on a credit card. I asked what card and they hung up.

Called saying I owed them money for a loan from Cash Advance

Need to find who's number this is

called back, automated message "Thank you for calling the career institute"

This number has called me, literally, 10 times today. They call once, when i don't answer they call back immediately. Then they wait a couple hours and do it again. So far, 10 times today, but it's 6:30 so i may get more.

For the past 3 days, this number comes up and they don't leave a message. It is a couple times a day. One day I got the "hello, hello.....and they said no more. I am getting tired of this number. If it is a solicitor, I had signed a form that I don't want those phone calls..... thank you.
