When I answered there was silence for a short while and after I said hello a few times an automated voice said "goodbye" and hung up. Weird, it was.

Called but left no message, came up as Potential Fraud. Blocked

Some people are using my NBN IP address and will be hacking into my personal account, they are calling to help me. I politely told him I am not connected to the internet, he laughed, said mother f@@ker how are you using your phone then, gosh I couldn't contain my laughter. He hung up on me.. lol beware.
