414-431-4451

The caller ID showed the # - 414-431-4451 and the 'name' that appeared was OAC.  Have no idea who/what this is.  No message was left.

same as above.  When questioned what it was in regards to man said "a personal matter".  When I replied, "if I can't get more information the call probbly will not be returned" he replied with, "he will know what it is in regards to just by my name."

I called the number back to see how they would respond and it came up as a collection agency of somekind.

OAC on called ID.

I have been getting calls from this # every week. saying this call is for - if this is - please press 1. I always press 1 and then it hangs up???

same things as stated above. Company called OAC from Milwaukee. Only they were calling on my cell phone asking for my daughter, a minor, and would not give me information about why or what the call was about. So she called them back and they wouldn't assist her either. All very secretive and automated....typical of what our world is becoming.

Someone called from this number and failed to leave a message.  I called back and they claimed I owed on medical bills, which is incorrect.  They did no validation of my identity and requested a copy of the check that I used to pay medical bills.  I think this may be a scam to obtain checking/credit card information.
