Rewards due to me were not paid

Hi,<br> <br> I have spent R3000at Sasol last month and should have been paid R150 rewards for that, however, I was only paid R87 for Sasol rewards.<br> <br> If i had not checked, I would not have known. Who knows how many people are being ********** in this way.<br> <br> Pleaase pay me the shortfall and compensate me for the inconvenience.
