Does the questioner want to ask "If a 4S store pays a deposit with a credit card, will a handling fee be deducted when the refund is made?" No buckle. According to the credit card payment rules, it can be seen that there is no prior notification of the need to charge handling fees, etc., and the handling fees will not be deducted when returning. The deposit shall be agreed in writing, and the parties shall agree on the time limit for deposit payment in the deposit contract. The deposit contract shall take effect from the date of payment of the deposit.
