Healthy heart score incorrectly downgraded.

My last fitness assessment was 15/12/2017. At which point all the scores were quite within the acceptable range. Recently, I was assigned all new scores as at Feb 2018 whilst my next assessment is only due 31/05/2018. I have emailed them in 19/03/2018 corresponded with Multiply numerous times via the chat. No one is able to direct me to the correct department, I haven't received any feedback. The consultants also refuse to provide me with the contact information for the relevant HOD. According to them my body fat is suddenly out of range, yet as of last fitness assessment and the one before it was within range. They are also unable to actually provide me with figure that was calculated or how it was obtained. Please direct me to the correct individual.
