810-275-0336 = SCAM. Legitimate companies do not call at 4:40 pm on a Sunday. Right there is a red flag ! I did not answer and they left no message. The "Do Not Call List" is useless !! Phone numbers are national now so although the internet says it's from Flint, MI it could be in fact from China.
The Do Not Call list applies only to telemarketing businesses.
It does not apply to charity calls or political calls.
It does not apply to misdialed numbers by people who are not making business calls.
