Who called from 9712201010

They called this AM, I did not answer, they left no message.  Tried to call and be taken off their list as previous callers suggested, but I received a repeating busy signal.  Really annoyed to be called on my cell.

Called my cell - left a message about home loan modifications!  I deleted the call and marked it as scam on my phone so I know not to answer it!

Just got a call on my cell. I did not pick up. They said the sent me mail telling me
how to lower my credit card interest to 1.9% but I had to press1. They said the got permission
to call me from my credit card company. This really surprised me because I don't  use credit
and I do not have a credit card. This is a scam

they call me daily, wake me up, I work nights. I have pusded take me off  your call list.  Doesn't work. And its my cell phone.

Received phone call... dead silence...
