What do I do if I get a fake currency note from ATM?

Suppose I withdraw money from some ATM and it turns out that one Rs500 is fake. What do I do then? I think the banks probably keep record of the numbers of new currency notes but what about old notes? Is there any difference between way of handling the issues of new and old fake currency note(s) from ATM? How can I prove to that bank authority that I really withdrew the fake note from their ATM?
