Worst service from Discovery!

A star was only selected as it had to be done... I have a query going back to February as my active rewards does not work. After countless calls and follow ups, to date after countless promises someone at Discovery is yet to get back to me... The same excuse is they are waiting for systems team to get back to then... I've spoken to atleast 20 consultants, someone in the systems team and also team leaders, it was escalated to management (can you believe that) and contacted them on their Facebook page.... Nothing has been done, of course...
