Received this phone number in an email from dlvalente1 @ optusnet.com.au as a number to call if I had any queries about the invoice that was attached. Invoice was for MYOB in the amount of $406.94. I didn't open it because I don't use MYOB & I don't deal with OPTUS, but I could see these details in the email preview. Just thought I would register this number here in case other people get the same sort of email. I'm so sick of scam artists & fraudsters & I think it's about time the government did something about punishing them severely.
