Vitality Gym Points

I don't understand why the vitality point for going to the gym have decreased from 150 to 100 without our concern and be notified.I feel the don't want us to reach those statuses to get more benefits.How do start giving a person a certain amounts of points and then decrease them with 50 points,percentage wise it does not make sense.They are greedy and don't know how to treat their customers.What happened to communication??????You can't get paid a certain amount then couple of years down the line it decreases,it is not not fair.ANGRY CUSTOMER.Why after so many years???
