Previously, a customer booked a car in Nanchang Hengxin Tianan Chevrolet 4S store, and the price has been settled. After applying for a loan, the car will be taken away soon, but the 4S shop will not sell it. You know, both sides signed an electronic contract, but they didn't expect to go back on their word at the last minute. Some details in the contract are unclear, so consumers are affected.
