Late Shipment Cannot Be Tolerated In the Future –
[Name, Company Name & Address here]
We are in receipt of the shipment for our order [order no.].
We would like to say that we can understand that due to large volume of orders, it is not possible for you to send all the orders in time, however we have been receiving our shipments regularly late since the last five times.
Although I know how busy you are dealing with different clients, I hope you understand that regular delays in delivery create many problems for us and, hamper our business.
We are planning to give you more orders in the future, but our only concern is fast shipment.
We are satisfied with your quality, and we want to continue to do business with you.
I would really appreciate your prompt attention into this matter. Hope you will do the necessary arrangements to send us the shipment in time.
