My caller ID said "Out of Area" for the number indicated.  I did not bother to answer.  Never heard of '000' being used as a prefix to a telephone number.

No they do not like being asked a question. You cannot even call the number back because it is invalid. I am sure that it is a SCAM. I do not know how the Attorney General will even find them. There is a website that they use to fool the recieveing caller with a phoney phone number. It is called GHOST CALLING. You can even use a phone number from someone else. I really feel that if the phone company would, that they have the power to stop it but it would cost them money.

THEY MISREPRESENTED AS CALLING FROM VISA/MASTERCARD HEADQUARTERS. I CALLED MY CREDIT CARD COMPANY AND THEY DON'T SELL MY INFO TO THIRD PARTIES AND DIDN'T CONTACT ME TO LOWER MY RATE AS CLAIMED BY THE MAN ON THE LINE. I GET THESE CALLS FROM THREE OTHER WIERD NUMBERS AT LEAST ONCE A DAY. THEY TRY TO GET YOUR CREDIT CARD INFO. I THINK THIS IS A SCAM LIKE THOSE EMAILS ASKING FOR YOUR INFORMATION SO THEY CAN STEAL CREDIT CARD NUMBERS. PLEASE FILE A COMPLAINT AT FCC.GOV TO TRY TO STOP THESE PEOPLE!

I have had multiple calls from them showing as "Name Unavailable" on my caller ID, but they never leave a message. I'm going to report them to the FCC as I am on the do-not-call list and this is some sort of scam I know.

DO NOT GIVE YOUR PERSONAL OR FINANCIAL INFORMATION TO ANYONE FROM THIS NUMBER PRETENDING TO BE INTERESTRATE.NET.
