Who called from 3133495000

They called my mobile phone.

Called my cell-i Didn't answer, didn't leave message, tried to call back from work phone...no ringing after a few seconds went to a busy signal

Got a call from someone who spoke with an accent, claimed to be from DTE offering a discount, I asked where she were calling from, she said Pennsylvania even though it was a 313 number.

Called mid day, I picked up but sat silently,  nothing for 15 seconds, then the caller disconnected. Obviously a robo-dialer for some spam call.   WIll be adding this to my block list.

Called my mobile, I did not answer and they did not leave a message.  Spammer
