Maintenance Fees

I realized that the government has changed the maintenance fees structure.
I went to the management office yesterday and they informed me that in my next month bill i need to pay for my parking lot maintenance fees as well.

Those day the condominium maintenance fees was calculated based on your house built up area but now i have to pay for my parking lot maintenance fees as well. If i have 5 lots i have to pay all 5 lots. 

Can any sifu/simo can verify if this is truth. If not i will shoot my management office officer
