My take would be that you initiate another FD. its simple and morose you should simply have instructed your bank to roll over.If you didn't do that,its not late,just ask your bank to initiate another term deposit for maybe 3 months.
No need to be scared cos once you do a new FD, the bank will issue you a new FD cert which you can upload just in case they ask for ADR for POF. Even if they call the bank,the new FD will be active and your bank will confirm.No cause for alarm.
But whoever told you a time frame you will get your PPR didn't do well. No-one knows how long it takes.Best bet is always to use savings or T.bills or FD of 6 months cos you can always liquidate once you have your PPR so money can be available to you.
