Discovery Vitality a **** or just a **** Show?

I have just driven to two Sportsmans Warehouses to try and buy new running shoes as it is D-Day, I then generated my 45% off Nike gear voucher to be used at Sportmans Warehouse and then pay the balance with my Discovery Miles that I have worked really hard to save up, all for the voucher not to work. The shop has said that I am not the first customer to have this issue and that many others struggle with this. Now my discount that I have worked hard for has been reset and I have to start all over again. I cannot express how annoyed I am. I have driven around, begged and pleaded, lost my discount and now can't buy what I have worked so hard for on the product that I so diligently pay for and comply with. A week ago I was on Vitality Travel and couldn't add my partner as a guest for our accommodation because of an issue on Vitality travel, I had to call in, book flights add that to my basket then add the guests details and at check out delete the flights... How ridiculous is this. There is an app for every Flippen discovery product, its actually outrageous! I want to have my voucher and Nike discount reinstated to my profile as I have now just wasted it on nothing, and in fact it has actually cost me time and money for nothing, petrol and billable hours that I wasted trying to get Vitality to just do what it is supposed to do. I am the first to rave about how cool Discovery and Vitality are but I honestly think anyone who is a customer of this organisation should just run for the flippen hills as fast as they can - Because from a UX experience its going for a massive ball of ****. Last week my Vitality drive card didn't work so I scanned in my slip and on the app it says it is DECLINED! WHAT THE ACTUAL HELL... It's a joke. To think I wanted to upgrade to a suite but I might just move elsewhere and make it my life mission to take everyone on Discovery and Vitality with me. At the very least I EXPECT MORE than just the reinstatement of my 45% off Nike gear voucher and my 23 out of 25 Vitality Fitness goals that I achieved!!!!!!! The word LIVID just does not cover how absolutely fuming I am. How embarrassing!!!
