Caller: Kevin Lewis (Telstra)

This person with a definite Indian accent claimed to be from Telstra checking our internet service. He knew our name, address and internet provider. He wanted access to our computer, etc.
He was very skilled - had all the answers and was very believable. When I asked if I could call him back he swiftly said yes and gave me Telstra's phone number. Fortunately, I was not taken in and checked with Telstra. HE WAS NOT FROM TELSTRA - A DEFINITE SCAMMER. BEWARE!!!

Recorded message claiming to be from Visa security department.
