Refund: Cancelled flights

I requested a refund from SAA multiple times to date but no response or assistance

I would like assistance with a FULL INVOLUNTARY REFUND due to Airline Cancelled flight for booking:

Booking Ref: LQ***H Flight: SA 286 - JNB to HKG Date: 16/11/2019

Passenger Details:

The initial booking was done through City Travel for 11/11/2019 but postponed to 16/11/2019 at SAA Offices at OR Thambo Airport where additional fees was paid by me DIRECTLY TO SAA as well.

Payment TOTAL= R9329.43 **(City Travel: R6969.43) PROCESSED

SAA: R2360.00 OUTSTANDING

The refund of initial ticket is already processed via travel company BUT however, there is still an amount of R2360.00 outstanding from SAA, which I paid to them directly to reschedule the flight which SAA cancelled eventually.

How long till the refund will reflect in my account AS SAA DIDNT PROVIDE ALTERNATIVES AND ALL ARRANGEMENTS HAD TO BE PUT ON HOLD!!!
