Support does not exist for Discovery Vitality

I cannot activate my Vitality Active Rewards form two different phones. When selecting activate on the feature i first do the health assessment, then link my Samsung Health App the progress to settings where i accept T's and C's. There after i get "Could not retrieve information. Please try again later” I get the messge from both my phones (1. Samsung Galaxy S5 and 2. Blackview BV8000 Pro). Each time when I attempt to reach out to you customer support centre I get disconnected all the time
