they call and don't leave message.  they show on caller id, but weirdly do NOT show up on the Vonage list of incoming calls.

Called here too... same sales pitch that I've received from about the last 100 calls over the past 6 months.   Actually called twice int he past 4 hours and both times they claimed they did not need to abide by the DONOTCALL lists.  They ID'd themselves as "Cresent Processing" and so I asked if it was the same firm as the one known as CPC.  He said yes.  I let him know that I was filing a complaint at donotcall.gov as we spoke and he got abusive and then hung up.

Same line as the others... they offer credit card processing services and there was a rep in my area.

This is a BAD business!!! HE asked for MY NAME and then just hung up! Maybe they're trying to get voice recognition. They ought to be reported, then arrested!

soft, sweet female voice asked for the owner

hung up when I told her "nah"

Called and asked for owner and then hung up
