Parking space price has not been announced, can developers accept subscription funds? Can I refund the subscription fee?

The so-called subscription of funds is because the developer did not get the pre-sale certificate, but it needs capital turnover, which is an operation of withdrawing funds. The deposit can be said to be earnest money, that is, the buyer expresses the sincerity of buying an item, and the earnest money paid in advance is also a deposit, because it is not a deposit and can be returned. If the developer defines the subscription money as a deposit when collecting it, it will not be returned. However, if the developer defaults, it needs to double the return of funds.
