**** R100 notes from Game store in Pretoria

I went ( 13/09/2018) to Game to buy paint and asked the cashier to give R900 cash back.. 3 0f the bank notes were **** (R100 notes). I only realized that they were **** on my way home after I tried to pay a taxi fare and the driver refused to take the money. I called the store and asked me to came back today 14/09/2018. When I got there the regional manager refused to hear my case and said there is nothing they can do for me since the event took place yesterday.. This particular Game store is at Soshanguve crossing, Pretoria..
