When you joined you knew you were not getting housing allowance and that you would never get housing allowance - yet you still joined CX = so you do not have a leg to stand on.
When you joined you knew what your mouthly salary, the amount of housing allowance, your retirement age, your p-fund contribution and that you should NEVER EVER want any increase or improvement in any areas of your condition - yet you still joined CX = so you do not have a leg to stand on next time you ask the AOA to negotiate with the company for a better deal.
