Bad service after joining Discovery Vitality

<p>I joined Discovery Vitality, effective 01 June 2016. I then called to activate my Rewards Card. In summary the agent informed me that they could not assist because of a system error. Two weeks later I called and there was some misunderstanding around where this card would be delivered (and how), mind you my assumption was that by now it would have been delivered or sent for delivery. They now say it will take three weeks to post the card. I feel that challenges on the Vitality side have somehow prejudiced me. If I wait for the three weeks, I would have lost out on any potential earnings and this is purely not my fault but discovery's (endless system errors). I now informed the agent to cancel my subscription and he tells me it takes 30 days. How can they take 30 days when they failed in the beginning? </p>
