Received at Wednesday, 9/17 at 5:41PM; did not answer and caller did not leave a message.

I found this information on another website:
"I received a call from 770-284-3312 on January 16, 2014, and I was told it was the Auto Processing Center calling with a vehicle specialist who would be speaking with me. Before transferring the call to the specialist, the caller wanted to verify some information. I said I was not familiar with the Auto Processing Center and asked if they were a department of a business. The caller responded that he was calling from the Auto Processing Center and wanted to verify information. He then stated my name and started to say more when I interrupted to ask if this was a sales call. The caller said he was not a sales person but that the vehicle specialist may offer a warrantee (or something like that). I asked to be placed on their do not call list. The caller did not acknowledge my request and hung up on me."

Called this evening at 7:45. I did not pick up and they left no message. Caller ID was "MCI Concourse" with the phone number of 770-284-3312.

Same here. Blocked.

Got a call from this number but did not leave a message.  They are now blocked!

Received a call from 1-770-284-3312.  CID was MCI Concourse.  I gave it the one ring pickup and hangup.
