Received many calls this summer from this number - no messages left. Appears to be auto generated calls as no one will reply if you answer the phone without speaking. Later we blocked this number only to be called by a new number from the same calling area (513-878-3669). After talking with the person on the line, it is definately a scam of some type as they are seeking your personal information (e.g. Social Security number). Just answer the call and harass them for a change.
Have no idea who these people are. They keep leaving static message in my voice mail. I called back and the guy (foreign, possibly East Indian) answers and says something like Genpact or Genpac services. I ask what do they do, he said it is a personal matter "what number did we call". Then I hung up.
After a little research found that This is Gen-Pac Services, a debt collector for GE Money. They also use: 513-878-4936, 513-322-3855, 513-878-3692 and others.
