Discovery Vitality is the worst

Hello, my name is Keitiretse Kupa, I'm a discovery Vitality member. I have I recently joined Planet Fitness gym after reading a contract that if I join gym and pay the membership before 31st December 2022 I would receive my joining fee in discovery miles. I joined gym on the 30th November 2022. I contacted discovery I was told I will receive the money within 15 days. On the 15th I contacted Discovery again, and I was told that those points are distributed on the 15th of every month and that I should receive my points by the 16th November 2022. To this day I have not received anything and ontop of that when I call the agents are not giving me answers as to when will I receive my miles. There is even a case number but my problem is still not solved. I had initially told my loved ones to join gym under discovery, I told everyone to not bother after the treatment I'm getting.
