No rewards points due to POS device issue

I had gone through to a Caltex service station to fill fuel and there was a problem with the POS device where the transaction was failing multiple times. The attendent mentioned that if he swipes on the nedbank POS device, I will not be getting any points from this transaction. I had no choice but to do this transaction. I had contacted the manager and he has asked me to contact Standard Bank as he can not allocate points for this. I require these points allocated to my rewards balance as this was completely out of my control and I have filled up at the required service station and expect my points. I had been to another Caltex service station after that and had paid with my card as usual and the attendent had swiped on a Nedbank POS device.When I queried it with him, he advised that the points will still be allocated. I would like confirmation that this is the case, alternatively I would like the points allocated to me as I have filled up at the require service station (A Caltex service station). I Wonder how many other Ucounts members have filled at Caltex assuming that they will receive points for the fill up.
