No cash in FNB atm's

Could FNB please shed some light regarding the availability of cash in ATM's in and around the Westville,Durban area.This morning,28 December 2020 was the forth time this month where I go to withdraw cash at the main Westville branch only to be turned away by security because all 3 ATM's had no cash,nearby local malls in Westville no longer have FNB ATM's including the local Bp garage..I then drove to Westwood Mall FNB ATM only to encounter the same issue(no cash for withdraw)..Is there something we need to know,FNB?
