Have had calls from this number - 313 235 2846 - for months without answering the phone. Finally answered and asked why they keep calling - they just hung up on me. I called the REAL DTE Energy and they said it was not there company.... and then later hung up on me when I asked for a supervisor.
I did call the REAL DTE energy and talked with customer service - Yes, they were about as helpful as calling back the 313 235 2846 number. Asked for a supervisor and after a minute was hung up on. And I pay these idiots to supply me with gas.
