I feel very differently about this! I am assuming that you have "invested" in the Legacy group. In my view the PDIC is simply doing it's job and making sure that only genuine claiments get paid.
When you say "genuine" I assume you mean the genuine PDIC member banks as listed on the PDIC official website?

The PDIC is an insurance scheme and no insurer is going to pay out on any uninsured claims
It is a Government insurance scheme and its rules are clear on its official Gov website. The opening of multiple accounts via wife and family including joint accounts were valid and covered up to P250,000 per acc according to their rules.
No good moving the goal posts now they have lost the game...
Well of course they can but then what foreign investor in their right mind would ever keep a Peso account here ever again? tsk tsk.
