Smart Shopper Points Theft

My points were ****** in January. I had approx R800 worth of points in January and in Feb Rnil. Upon querying it, was told my cel number had been changed on their system, and my points had been converted on a mobile app and Airtime had been purchased. They investigated, and I was told they could do nothing, it was someone who had access to my ID number. Low and behild, the few points I accumulated in Feb were ****** yesterday, while my acc is under investigation, and all they say is: there is nothing they can do. I cant cancel my card and apply for a new one, as everything is linked to my ID number. Shocking!! They havent bothered to contact RICA to see who's number had been registered on my profile. So much for client service.<br>
