Less Rewards yet again, why Discovery??

Vitality is supposed to be a REWARDS programme. Discovery is getting worse and worse by the day. Vitality is R400 plus per month for our family of 4. Already lost tons of benefits by switching to Dsicovery Bank. Now the Vitality rewards which we had left with Vitality are being converted to miles. Fine....but after playing the board today you earn 50 miles which is equivalent to R5. Cannot even get the cheapest coffee on the rewards board. Highest miles pick is 150 which is just enough for a coffee if you are lucky enough to select that tile. Been loving the Vitality Rewards programme that you worked so hard on implementing before. Seriously just cant fathom why we should stay anymore, less rewards across the board, frustrated and horribly dissapointed, used to love all these benefits. We have been so loyal and really good customers of all your products for more than 15 years. Whats the deal, why???
