Rude guy telling me he was from Telstra and that he urgently needed to talk to me about my computer and telecommunications. When I said I'm not with telstra he told me I was lying so I hung up, he called back six times - told me he loved me and rambled on that he didn't work for telstra and was lying. Very creepy - obviously a call centre heaps of noise in the background. When I called the number I got a recording about it being Blackwoods, the big safety suppliers. These jerks are somehow mimicking a legit business number.
