Same for me as for Madwoman. Constant calls for the past week. I have purchased a blocking phone system, but M Thorson's message is a downer if the system doesn't block entered numbers. So frustrating, and I have fantasies of a person like "you know who" visiting these scumbags and doing the world a favor.
I am receiving about 5-10 calls a day from these people. They are Indoor Air Solutions. My caller ID also has them as Ansaphone. I reported them to the Do Not Call Registry and also advised their answering machine to take me off their list. Doubtful the calls will cease, but I just keep answering, leaving the phone off hook, until they hang up.
Person calling didn't pay any attention to the fact that they were talking to an answering machine. Said she was calling from (undecipherable) systems and asked for me by name, kept saying "hello" when she got no response from the answering machine. Caller ID did not show company or state, or any other identifier, only phone #. How much longer must we (consumers) put up with these obnoxious calls, since DNC obviously means absolutely nothing. As several other complainants have noted, we don't seem to have any recourse and for people who don't have caller ID, such as some elderly folks, this is an epidemic we should be able to cure.
