Vitality sucks

I joined discovery in november 2016 and activated just about every rewards program. I though everything was going smoothly until I went to clicks to try and spend my cash back and was told that there is nothing on the card. I called to enquire and was told that it will take a few days. I waited a few weeks and was again told there is nothing. I then had to do some admin but eventually I was told I can spend my cash backs, not using the card but rather the card number. Months later I hear that I deactivated the healthycare benefit. I tried to activate it but get told to contact clicks. When I contact clicks I hear its active I need to contact discovery. I've done everything I was told to do by discovery to get the issue resolved, several queries have been logged. I've been to clicks and called them many times. I even followed someone's advice to get a new clubcard. Can someone who knows what they are doing please get this resolved because I'm stressing myself into high blood pressure over this problem.
