Fnb cOvid relief ****

I app**** for covid relief for my car payment of R2500 a month. This should amount to approximately R7500. Recieved a "relief" of over R8100 (loan). I'm not sure if interest was added in for the year which is not fair as I planned to pay it off within a few months. Also the debit order still came off my normal account so what do I owe this R8100 for??? I want to cancel this so called relief before using it.
