I cannot redeem my vitality reward

I qualified for a Vitality reward at Kuai . I visited Kuai at The Point Virgin Active Gym in Cape Town and the attendant at Kuai tried retrieving the reward code from my phone but it displayed a blank blue screen without any bar code or voucher number. <br> I emailed the complaint to Vitality on Monday . I received an electronic email that they received the query and sent me a reference number *** . It's Friday afternoon now and after emailing 3 more times and receiving reference numbers *** and *** my query is still not resolved and they have not responded to me not once. I have tried calling the call centre on *** and that has cost me more than the reward itself. <br> The 1st weeks reward has also expired on Wednesday so I tried redeeming my reward for the next week and it's the same problem. A blank blue screen appears on my cellphone. I have sent pictures of the blank screens via email to Discovery and also info that I am using a Samsung Galaxy Note 3 phone and the Discovery App is Version 5.7.0 . <br> Please assist me . My 2nd reward also expires on Wednesday. <br> DISCOVERY CAN SMS/WATSAPP/EMAIL ME MY REWARD VOUCHER. <br><br><div><em>(Supplier name changed from Discovery Health to Discovery Vitality &amp
