FNB Covid relieve only a money making scheme

Due to the Covid 19 pandemic I was forced to make use of the Covid relieve offered by FNB. Only one problem...even though we have a contract in place, stipulating that for a certain period of time they would make payment on my accounts, and after that period lapses, I would start to make payments to them, I am getting notifications from FNB that I am late on my credit card payments because THEY did not honour their side of the contract!! Not once, but twice now this has happened! And neither a personal banker nor their online "secure chat" (should be called wishfull chat because its wishfull thinking that someone will actually attend to your message) can assist you, only citing "system error" as the reason for their failure to honour their contract.
