Got a missed call ... no message left. Rang it back and got the recorded message "This is the National Australia Bank, your call my be recorded for......"

Well actually Mr Smarty Pants, I am not a customer of any of the credit providers you mention. In fact, I don't even have a credit card! Are we still being paranoid or simply not wanting our time wasted by telemarketing?

Who is this... I got 6 calls from this number within an hour one evening. I answer and they hang up. .?

It's a call from a credit card company regarding late payment, that'd be the only reason for this call. This number services HSBC, Visa, Woolworths Money and many others. Pay your bills and stop being so paranoid about phone calls.

There seems to be multiple numbers they use. I also got numerous calls and have them listed on the do not call register but it doesn't seem to stop them. I've had calls at 10 pm at night and now refuse to answer any calls from an 03 area code.

Just recieved a call from this number claiming to be from Visa card.
Treated it as a gottcha call.
Let him have it!! then he hung up.
Bloody annoying these prank calls.
