How should I react if I refuse to accept the house?

You can not accept it for the time being, and you have to pay the property fee when you accept the house.

However, there is a time limit and the house will not be closed for a certain period of time. The starting point for calculating the property fee and heating fee should be the delivery date agreed in the contract.

During the period of repossession, if there is any problem, you can report it to the developer and suggest repossession within a time limit.
