They are not in Detroit (DETZN 4), They are not in Dearborn either. They are scam and rip off artists that spoof numbers and have several they call from and they are probably not in America. They try and get through your blocked number setting with a spoofed over number. The "Do Not Call" list works for legitimate businesses, it doesn't work for criminals. Criminals that want to steal your money or identity don't care about our laws. There is not really anything that the FCC can do about people outside of this country. Today we just have to try and deal with these idiots who's intent is to steal your money or identity. Get a call blocker, don't answer the call or just ignore it, especially when you see all the posts on here confirming that this is scam call.
The other numbers they use are as follows: 313-307-4196
313-307-4195
213-217-9999
All three of the above numbers are the same people trying to rip you off. I'm sure there are other numbers too. Unfortunately, there is probably more of this to come. Just try and stay on top of it. My phone can block hundreds of numbers so I do recommend looking into the different types of call blockers. There's all types. They put power back in your hands and so does this website. :)
