Clicks Loyalty ****

I have had a Clicks card for a very long time. I had to get a new one 4 years ago and ever since all my cashbacks has been disappearing. I found it odd that I kept swiping and never had any cashbacks. Then about 2 months ago I was told there are R300 on my card in cashbacks by a Clicks pharmacy. I tried to use them a week later and they were gone AGAIN! I have sent several emails to Clicks to no avail. So, this whole Clicks loyalty program seems to be one huge **** or something is wrong here... I am going back to Dischem where I used to be and always got my cash-backs and my savings.
