In the mail I received a letter offering a Google AdWords $75 free advertising trial. However, after following the instructions to register on the Google Adwords site, I was told that the particular voucher had already been redeemed. Is this some sort of scam?
I tried calling the phone number on the letter (there was no email or street address for "Jason Chuck, Head of Marketing, Google Australia and New Zealand"). I got a recorded message: "All circuits to the destination you are calling are busy, please wait a few moments and try again".
