Corona virus pandemic

I was employed by vaal toyota sasolburg in march and due to corona virus pandemic i was told to stay home and they will call me when they need me and that they have applied to the government for the employees which earned less then R6500 and that they should stay home and recieve R3500 during the time of corona virus pandemic. I was made to work for the month of june and got the payment for corona in july and i havent been paid since. I then contacted them to ask for a termination letter so that i may start applying instead they told me to resign. And i havent heard from them since .
