Who called from 4155551000

They have been calling my DNC number for two weeks. The people just say sorry and hang up on you when you call to complain. Palo Alto is in Santa Clara County so the San Mateo DA cannot do much. I have repoted to the DNC site

I'm purchasing an airhorn to respond to the live person.
Maybe that will clean her carpets!

I am on the DNC list and there was no remove from list option.

Another carpet cleaning call -- same as the others -- filed complaint with FCC41

I received a call today that began with a recorded message about carpet cleaning. I pressed 1 to make an appt. (really to talk with them). The woman who answered said she was with "Best Carpet Cleaning". I began to tell her I was on the do not call list and she hung up on me before I could finish my sentence.
