Unsolicited calls from Carpet Care

I have had the same experience as Martha concerning unsolicited robo calls from Carpet Care.  One call was made at 8:30 p.m. on a Sunday night.  I, too, had to press "1" in order to reach a human in order to find out the name of the company.  When I told the person who answered to stop calling or to transfer me to a supervisor, she hung up. I will also file a complaint with the Do Not Call web site.
