HealthyCare benefit cancelled without my knowledge

We used to be very happy with Vitality. Being Diamond status we enjoyed cash back rewards from Clicks and the Healthy Care benefit. We used to receive AT LEAST R1000 of vouchers EVERY quarter. This year we suddenly only got R100 if we were lucky. Upon further investigation I discovered that Discovery 'auto-cancelled' our enrollment in the Healthy Care benefit without our knowledge, meaning we lost out on a few R1000's worth of vouchers. After being promised we would get these benefits back I had to get manual transaction listings from Clicks, and after submission of these I had to deal with very bad customer service. I was promised a call-back more than 3 times without it actually happening. I was promised resolution of the problem more than 3 times without it ever happening. More than a month and a half has gone by since I picked up this problem, and still we don't have any cash back. This, in my opinion, is *******.
