clicks clubcard

I am disappointed with the clicks club card rewards system as i use my club card at engine garage to pour petrol in order to receive points. i checked my points and it shows 0.00 points, i work 60km away from home and normally use engen garage Bassonia to fill up and swipe the clicks card for points, the question is a we really rewarded for every litre we fill up or we get points when we only shop because its highly impossible to use the card more than 3months and not get points.
