ClubCard points not allocated

I have become fed up with Clicks' new ClubCard points system, where points are apparently loaded onto the ClubCard. I've spent around R1,000 at Clicks in the past few weeks, and for some inexplicable reason, my till slips no longer display the number of points I've earned, and the website shows that points haven't been updated. I've written several times to the consumer 'service' line to query this, and they're either unable or refusing to respond to my request that my points be added to my card. I'm furious, because I've been a ClubCard Gold member for more than 20 yrs, and I've never had a problem. But these issues are making me seriously consider taking my custom elsewhere.
