Got the same call. Tried to talk to someone but accidentally disconnected it. I think, based on an earlier call I got asking me to call someone at 989-259-1597, that this may have been someone from Energy Choice trying to sell us alternative energy choices. If you call the 313 number back, you get a recording offering to remove you from their call list. So I did.
313-209-6331 just called caller ID says notice. Recording Telling me I can lower my gas bill. Hung up on it. Had enough of these scammers. Last one claiming they were with the gas company got nasty with me when I said they would already know the name and address on the account if they were legitimate.
