I received a text message on Sat afternoon, telling me my new password for the Net Bank account....I was going to delete it thinking it was a scam....
then I find an email message giving my new account number...for same
I was almost convinced it was scammers on Sat arvo
went to the commsec site, and found they had opened a new account in my name....
I have never heard of this before, without my consent, plus I dont consider it safe to send my account details and passwords over the net
I have to wait until the bank opens Tuesday to find out whats been going on...and to let them have a full blast of what I think about them
geeez
