Discovery Vitality POOR Service

My profile has been de-linked from my husbands profile for the third time in a year. No explanations, just suddenly I went from Diamond status to Blue status. My gym visits for March (when we joined) and April not reflecting. After many emails, still no joy. They just say that they allocated the visits from when we joined, which they say is from May. There is just no winning with these idiots managing my profile.
