They also call me from 905-638-2475.

Air duct cleaning services.

I answer the phone, but they hang up all the time

Received this call without any message.Just ignored.

Received this call twice this week.  Haven't been home, but have call display.  It says that the number is assigned to an S. Epstein at 97 King High Avenue in North York.  Are these people duct cleaners?
