How to send text messages when there are too many goods?

Tell the customer the actual reason. Due to the large shipment volume and busy warehouse, many new people have been added to the delivery staff, which makes it more troublesome for customers to return goods. If it's far away, the customer doesn't have to pay the freight. If it is close, the freight is paid by the customer. If the freight is too expensive, you can negotiate with the customer and let him pay for it. Just deduct the freight from the payment when the customer places an order next time. Sending the wrong goods is a situation that will happen to every company. I trust customers.
