Please Investigate need this person to be stopped

On the 31st of September 2019 i went to Cambridge food in Vosloorus normally i do my groceries there,I paid my groceries using my bank cards mine and sisters i was helped by cashier no:732 and the time was 09:43:40,Invoice no 22#068159. I went home straight after that didn't pass anywhere ,round about 18h33 first sms came through my money was withdrawn,18h34 my money was withdrawn again,the third time it declined cause i assume the person tried and nothing was left I called FNB to block my card .

Reason why i assume its the CAMBRIDGE staff cause last time i saw my card i was there and only that day went to the store and i used my card there and the cashier i think she saw my pin and why was my card only used after Cambridge closes at 18h00,whoever waited for the shop to close to go and use my card immediately after knocking off.Last time Cambridge gave us rotten meat we bought a hamper and we always spend more than 2000 at this store.lease Cambridge management help me investigate this i need my money i am in need i do not understand how someone be so cruel like this and surely its someone who is used to doing this to customers.My number is ***.
