First of all, your intention is to have a provident fund loan to buy a house. If the intermediary approves, you need to have the terms of the agreement, and the verbal commitment cannot be used as evidence. Therefore, if there are clauses in the agreement (the payment method in the house purchase contract includes provident fund loans), the house purchase can be cancelled and all the money can be recovered based on the intermediary's breach of contract; Without an agreement, you earn a commission to cheat customers into buying a house (many intermediaries cheat customers into getting rich commissions through various means). There is no law to protect you because the law needs evidence to support it.
