Tianjin Sunac Yao Xing Wuzhou breached the contract, tricked me into paying the down payment, raised the property fee privately, and refused to return the house payment to me. What should I do?

1, you will be fined if you check out;

2. Your problem is to raise the property fee privately, and you can completely reflect this problem to the relevant departments;

If you insist on checking out, do it according to the contract. If you have paid off the loan in full, this house is not refundable, so in order to reduce the cost, you can only complain to the relevant departments, such as the property management office.
