Discovery manipulating results to push for high premiums

I got the shocked of my life when my vitality results were manipulated by Discovery. The aim was for me to fall outside the specified value so that they can push me to Select or Standard which will result in a high premium. To me as their client its vicious & disappointing coming from Discovery. A BMI of 28.8 compared to the 31.1 they gave me cant be a mistake but deliberate. Please sort this asap
