this male wanted $350 for return of $4,000

Of course it's fake. I got a similar call today from the same number.  The guy claimed to be Michael Schnader from Money Saving Expert.  He was a bit rude when I asked him to confirm some details.  I said it was a bad line and could I call him back.  When I called back on (02) 8005 4727 a different guy answered, without giving a name or company name, when I asked for Michael Schnader he said that was him and he made a similar pitch about me being entitled to refunds of overpaid bills, taxes and bank fees.  But I could hear the first guy in the background making another similar call to someone else. The second guy also said that Money Saving Expert is an Australian Government Department.  When I said no it's not, he asked if he could call me back in 5 minutes.  I said no thanks and hung up.

this person who calls me,tells me i have money owing to me and gives me another number to call and then that person ask for my bank account details,and if i dont he gets abusive.

so is it for real or not?

is it real or fake??

I got the same call and he got angry when I asked for more time to verify what he was telling me and I asked for some sort of documentation but he said there "was none"???
