Total attendents does not swipe your Dischem card at Total Kempton Park Monument road

This morning I drive to Total Aston Manor Kempton park (RAF Transport). I asked the attendant to fill up my car. This was at ****. He filled up R 1133.35. He asked my bank card and swipe it. He asked my dischem card, take it and walk away. He came back and said it was swiped. I asked for a till slip and noticed that my dischem card swipe does not appear on the slip.
