Caller with an Indian accent claimed that they had discovered fraudulent activity on our credit card. He said the card number started with a 4 but would not give me the last 4 numbers on the card - he said that was a security risk. I asked him which bank and he said they were calling from the Fraud department for Visa and Mastercard. Claimed not to be connected to a bank.

Claiming to be from Telstra, about my internet connection. I don't have a Telstra internet connection...
