@Tom these guys are usually based out of countries that either have no laws of the type you describe, or they're so poorly enforced they might as well not have them. Anyway, got the call around 11 AM on a Sunday morning. Didn't answer; left no message.
no answer when i answered as well, but i have recived a call from this number before and belive it was for air duct cleaning service that deffiently sounded like a scam because they would not take no as an answer
Have received multiple calls from this number. The last call I hung up without saying anything. They called back immediately and were abusive and aggressive.
