Diamond status means nothing at Vitality

I am writing this review not because of the their customer service but their inability to rectify a mistake that they made. I worked hard last year to achive diamond status on Vitality, just for it to be wiped away at the start of January. I went from diamond status to silver without an explanation. After calling customer care i was told that i did not reach the required points to get diamond even though i was diamond status at the end of 2025. It has been 2 weeks of back and forth me giving them recommendations on how to solve this problem and it is still not fixed.
