Caller: Scammer - "Do Not Call Register"

Indian accent. Call centre (lots of background "call centre" noise). Bad call quality. Said he was from the Do Not Call Register, "part of the Australian government". Claiming my credit card expired and needed to be updated. Phishing for credit card information, trying very hard, asking me to "confirm" my credit card expiry date. Basically I told him there was no chance I was going to divulge any information from my credit card whatsoever to a phone source that I had no way of authenticating as bone fide. After about 10 minutes of this he said "OK, I will disconnect your landline phone then". Moron.
