Recorded call, refused to ID self, no opt out. Hit number 1 to make appointment. System then hangs up. When called back its from blocked number. Person won't say name of company when asked, only Carpet Cleaning. When pressed they hang up. The next time I was called by the recording and opted to make appointment I stated I'm on do not call list, they hung up again. Next time I will make appointment and when tech appears I will press him for business license information, not name of service on van. Ridiculous that this must be done to stop illegal telemarketing calls.
