They will call 3 times within 2-4 minutes. When I answer he says "this is Joe ( or John, etc can you hear me" . Some times none says anything. They cal from Dearborn Michigan on several numbers - 313-367 -4212, 4218, 4240 etc.
Yes man i have been getting 3-4 calls a day from 313-367-42** numbers as well they won't quit. Its the old "can you hear me" scam. Really pissing me off. Just going to keep blocking them and hope it stops.
