Foreign accent, has rung on several numbers, always hangs up. Do not give your name, but ask him to give you details about your account as he claims he is a Telstra Technician, even claimed he was working from 243 Exhibition Street Melb. He could not explain why his number started with 07! This guy is lying little toe rag!!!

Same as above, claimed he was from telstra and wanted to show me, on my computer, where the problem was. I told him it was a scam, and if he was from telstra to send me an email about it. He hang up !!

Someone with foreign accent perhaps Indian asked for Mrs. XXX. (XXX is a part of my company name). Obviously this caller cannot tell person's name from company name. When I asked back, he just hang up.
Very unpleasant.

Said it was Telstra calling about internet, I played along for a bit, he asked me if I was at my computer as he was going to give me a code to put in to stop scammers, of course I didn’t even have my computer on, I did ask if I can call him back as I was busy and he said I will give you the number and guess what??, he hung up!!!!
