FNB ERROR CODE: 50 - Being unduly impoverished while FNB gets unduly enriched.

Apparently FNB do daily maintenance on their systems and thus customers cannot access their 32-day savings accounts between 21h00 to 03h00. This means that if any debit orders should bounce as a result of me not being able to access my own money they will not be liable for it. If I wish to access my own money during this time FNB with charge me a penalty fee 100% more than what it usually is. So the money is accessible but only from their side and only at double the cost. ERROR CODE:50 FNB. Shocking! Being unduly impoverished while FNB is unduly enriched, the very definition of an ******* transaction.
