They called, I didn't answer, this is the message they left:

If you are not (Deza), please hang up or disconnect.  If you are (Deza) please continue to listen to this message.  There will now be a 3 second pause in this message.  By continuing to listen to this message you are acknowledging that you are (Deza).  This is "Creditor Advocate", this is an attempt to collect a debt and any information obtained will be used for that purpose.  Please contact me about an important business matter at 866-357-7522. Thank you.

I'm actually impressed that a debt collect left a message.  Not sure if I trust it for just that reason however.

Not 100% sure who they are. They were calling for the person that used to have the phone number before me. Recorded message said to call 866-357-7522.
