I've gotten many calls from this number and I've never answered.

called 8/11/16 7PM

Caller claims to be calling from DTE Energy then asks if I am a DTE customer. Must be a scam. I have a signature card on file that I have to sign before I can be switched,

Claimed to be from DTE Gas. When she answers or responds.   I think they would say DTE Energy not DTE Gas.  To offer me a 30% discount on gas. She is very hard to understand. I would think that DTE would hire people the you can understand.  I just hang up.
Continues to keep calling!!
I have now blocked the call.  With these calls reported why doesn't DTE Energy follow up on them and other companies!!!!!

Just called and looked up the number here before I answered! Sounded like a VERY BUSY call center overseas as I could hear plenty of conversations in background not in English. Told them I already knew it was a BS call - the woman swore, hung up immediately and I blocked any further calls from that number. Thanks for the heads up y'all
