Who called from 3123270508

I have received calls from this number and they hang up when I answer. Also other 312 area code numbers.

Caller hangs up when I answer my  landline.

said I won a suv on call messages also called my father I guess they have alot of suv's

I received a message from this #.  He says his name is Richard Hugh (?) with the prize distribution center and he is calling in regards to a contest I entered some time back about winning an SUV.  He says that the contest has now ended & he has great news for me.  I need to call him back in the office at 866-430-3177.  He looks forward to hearing from me and congratulations.

I got the same message on my answering machine.
I never entered a contest.Plus he never said my name
throughout the entire message. He was random.  Its a scam.
