I agree with you.
If MO count into the Mgt fee then Flat D & E have to pay more but every unit got 4 cards. Is it fair??
Therefore what we can do is if you got 2 persons then ask your neighbour also got 2 therefore we can share the fee.
If you think is still expensive then not to join them after 3 months free. You still have the rights to use swimming pool. (most of the estate only have swimmimg pool)
What I concern is after we pay the membership fee what else we need to pay for using facilities ?
