Air Duct Cleaning telemarketer.
Lady with asian accent wanted to offer me a special deal on air vent cleaning.
When I asked what company she was calling for - she said American Airflow, and when I asked where they were located - she said Oakland, CA.  So I asked her to remove my number from their call list as required by law, and she said OK and have a good day.
The number is probably spoofed, and seems to belong to a completely different local company.
