If the two parties have signed a contract, but the contract puts full responsibility on the consumer, in this case, no matter what the circumstances want to return the deposit, it can be recovered. If there is no problem with the contract signed by the two parties, it is due to the merchant's breach of contract first, it can ask the merchant to compensate for twice the deposit. On the contrary, if the consumer wants to terminate the contract for personal reasons, the merchant has the right not to return the deposit.
