did not leave message, stayed on phone til end of voicemail

Collection agency.  I answered their call this morning at 9:32am for a Capital One account.  I told them I paid it off last November with another Agency.  Again at 1:48pm they called my cell phone inquiring about the same account.  They called me on a different number and a different phone this time.  I asked them to turn on their recording and I told them they are in vioation of federal law since I had already talked to them today.  I told them if they call me again today I will file a lawsuit against them!!!  He became rude and told me the only way to stop the calls was to make a payment.

Rude calls at work and my cell...Please make them stom

I have filed for bankruptcy and notified all creditors.  How can they still call?  Is this a scam?  The never leave a message.

When I call this number back, they answer "hello".  It is a collection agency, and one that uses backdoor tactics.  Collection agencies have their place, but these guys are scum.
