Received call and let it go to voicemail with no message being left !! I called back and recording said that the number is not in service. Looks like the telemarketers have a new numbers!!

Shît head duct cleaners doing a turn over of phone numbers. Blocked the number after the person said nothing.

I don't get the scam. They say they are duct cleaning but it sounds fake. With zero customer service or good English it makes no sense. Either way I blocked them.
