The DAY i got my new cell phone number, this number began calling me. I believe my call history shows that they've called about twice a week for a month now beginning on the day i got this phone. Is there a way to block it?

I receive a call per day from this number.  The recording gives a return number, which is Active Credit Services.  When I called and asked to speak to a manager, I was told they were looking for someone I didn't know.  I was told the only way they would stop calling was if I put them in contact with this person, or gave them my home address.  When I refused to give my address, the manager told me "if you won't cooperate, we can't do anything to help you".

Started getting calls from 503-000-0000.  Got home today and caller ID there were 10 calls from the number today!  Have answered twice and there has been no one on the other end of the line.

I get this call all the time and that is what is in the caller ID. Anyway it always is a recording. It says in a Ladies voice "This is a CSI and I don't answer or call back. Because that stands for Crime Scene Investigation and I know that nothing like that is here. I don't answer it. They need a different response if it is a Debt Collector or a Telemarketer.

From this website I now know that this is Active Credit Services Inc. But when I answer the call, nobody's there and no instruction as some have said. My concern is it is a new telemarketing ploy, to get past the no call list.
