(561) 515-5011

This is a telemarketing call center for U.S. Air Duct Cleaning and they use a dialer caller ID of (561) 270-4166. If you try to call back recording says number not in service (common so they won't get traced by Do Not Call List). I set up an appointment and they called me from a call center (561) 515-5011 to confirm and advised the name of the company was Air Duct USA. They also use a (954) 900-6838 to the call center too! I have reported this to the FCC.
