My husband and I have received about 10 automated calls in the last 2 weeks from Premier Carpet Care trying to sell us carpet cleaning services.  
I just called the company to complain about this, as my husband and I are on the "do not call" registry.  The person who answered the phone denied that Premier Carpet Care is making these automated calls.
He suggested that I call the San Mateo District Attorney as someone is making these calls against Premier Carpet Care's wishes.  I just left a message for Chuck Finney, the San Mateo County Deputy District Attorney at (650) 363-4097.

I just got their call again at my home phone - recorded female voice from a carpet cleaning company. When I dialed the number, there's no ring and the line eventually clicks off. So much for the Do Not Call list.

They called six times. Three of the times I pressed "1" and successfully set them up with bogus appointments at various addresses in my neighborhood. They're using the 888-279-6050 number these days.

I keep finding this number on my answering machine without message. It is really annoying.

I've had at least 4 prerecorded calls from the same carpet cleaning service. Googling the number shows this is not limited to the local area.  

They have given at least 4 names (at different times in the same call). I actually had somebody come out to
try to find out who they were.  The person came in an unmarked Ford Taurus
station wagon.  His estimate sheet said "Daniel Carpet Cleaning", with no
address and the same toll-free number in the pre-recorded message.  I asked
for an address, but he refused to give it to me.  Daniel Carpet Cleaning
does not show up in any local searches as being a real business.  The CID on
the prerecord is spoofed.

He called his boss and had me speak with the boss.  Both the boss and the
worker had heavy accents (Eastern European??).  The boss essentially
threatened me, stating that, "What you are doing is dangerous," and, "we
know where you live."

Nice guys...
