Sasol Garage review: Service from the cashier

I was at sasol garage in lynwood road pretoria on two occasions assisted by a lady named tokyo I m disheartened in the delivery of her service, first I bought airtime n told her that I once bought she said it might not work n I told her I bought it before I finished talking she printed it n it indeed did not work n she just did not seem to be bothered, secondly today I bought bread the price I saw was 20 bucks on the shelf when I get to the till she said it’s r22 and I told her I saw 20 bucks she just did not even go to check n charged me 22 rands. I relally don’t like her service n enjoy shopping there please train her properly as she is incompetent
