1. First of all, express a sincere apology to the customer and appease the customer's current mood.
I can understand that you are feeling the same as I was before, but good things have to wait. Inform them that this is our best-selling product, and the factory production volume is very high. Big workers work overtime at 12 o'clock every day. 

2. Ask the factory about the latest production status and when it is expected to be completed. 

3. Tell customers that we are very strict about product quality and will do tests before leaving the factory. You can get it in the future as the best product, then send some factory video pictures appropriately.

Dear Sir, Thank you very much for your order.But I'm very sorry to tell you that we can't meet your target shipment as it is really urgent (only 5 days) As you know, it's peak season now, so the production times of all factories are a bit long. That's why I ask you to confirm the order ASAP. We will try our best to get the goods ASAP (about 15 days), but we can't accept that a one-day delay will require paying US$500. I believe that nobody can accept this point either, and I'm sure I have offered you a fast delivery date. Thanks for your understanding and support.
