I called them back from an unregistered prepaid phone. No answer.

I received a robotic call offering carpet cleaning services.  At the end of the message it said press 1 for a live person.  There was no opportunity to opt-out by pressing another number, and after a few seconds it detected I hadn't pressed anything and disconnected.  I am on the national "do-not-call" list, by the way.

Same as the others....I'm on the do not call list and they're calling anyway to offer to clean my carpets.  When I got a rep and asked to be removed, they hung up!  GRRRR!!!!

Same here.....

I'm going to run out of space in my call block feature.  And another unwanted call.  I didn't answer, they hung up.
