Recent flight with SAA

I was on flight SA204 from JFK to JHB on Saturday 26th July 2019. I was requested as per airline safety regulations to stow my handbag in the overhead compartment. Whilst on this flight I had all my cash ****** from my wallet when I was asleep. The money was inside my handbag in the overhead compartment. I am disappointed that this can occur on our national airline whilst passengers are sleeping and the aircraft is in darkness. I would like this situation to be resolved by SAA ASAP. Please contact me
