total scam. i called police and they said they have these guys on record. inform police.

got call from jenny williams said that calling from ato and won  
$10000

Got a call from (02) 9793 7714 said I won 10000 from the ato and to claim money had to call (02) 6100 3584. Feel sorry for people that would fall for this scam?

A lady called me and said that I have won $ 10,000 dollars from ATO then she gives me a reference number, A 786 with telephone number to call, said this is ATO number; (02) 6100 3584 I rang to check out, I spoken to Mark he ask me what is the reference number I gave him the reference than he ask  how would you like to collect it,  given options POST OFFICE, COMMUNWEALTH BANK, OR WESTPAC BANK; I SAID Commonwealth bank , he said please identify yourself; now I know he came to real point all he wanted is my identity for fraud ; Be careful of this peoples
