Discovery drive vitality

I have sent numerous emails to discovery, with limited replies. My vitality drive rewards does not seem to work on my app for the past few weeks now. The vitality app keeps stating that it needs to refresh, but nothing happens. I have no missed weeks of not being able to play the gameboard, as well as not being able to redeem my rewards. This needs to be fixed.

Discovery seems to be able to contact me regarding sales, but not regarding any of my queries
