Vitality failing to reward the customer

I joined Vitality in November and since registration it's been a mess. It started off by Discovery processing my registration with a starting date 1 month earlier than what I've indicated. From there it's been the one system issue after the other. I've logged 3 queries simply because my active rewards points don't calculate and give me the rewards (which is the whole point of Vitality from a consumer perspective). Activating my HealthyFoods benefit was an issue, because the system wouldn't allow me to complete the registration due to some bug. Even logging into my Discovery profile was a challenge as the login box disappeared every time I tried to type in my password. The vitality age assessment was a challenge to complete as the system didn't allow me to proceed - I had to do it multiple times. Now I don't even get my vitality cash backs either. Even though I spoke to 2 different consultants to update my banking details and updated myself online I'm told that I there is no banking details on the system... Seriously Vitality, you need to sort out your systems, this has been a terrible customer experience. Every time I need to spend my time to sort out something that is suppose to run like clockwork.
