They said that they are a bitcoin information provider and they help you get started. Didn't believe them as they were really pushing for it.

Three days in a row I had missed calls. Numbers were (02) 7252 2532, & (02) 7252 2564 , and (02) 7252 2536. On the fourth day I answered. He was quite rude. And he kept insisting that I had registered asking him to call me. He wanted me to invest and I said sorry I don't want to waste your time. He was very rude , insisting I had asked for this call. And then when I said I'm not interested he was very rude and then hung up !

Have received calls from (02) 7251 2576, (02) 7251 2583, (02) 7251 2589, (02) 7251 2590 and (02) 7251 2599 in last 3 days and they are all scams trying to get me to invest.
