Dear Sirs,

Your shipment(装运)of twelve thousand“Smart”watches was received by our company this morning.However,we wish to make a number of complaints concerning the serious delay in delivery and your failure to carry out our instructions.   

It was stressed from the beginning that the delivery date had to be less than six weeks. While we appreciate that delays in production are occasionally unavoidable.We must point out that the major reason why the order was placed with your company was that we were assured by you that your existing stocks ensure immediate shipment.Late delivery of the goods has caused us to disappoint several of our most valued customers.and is sure to have a negative effect on future orders.

The second complaint concerns the difference in colour.Only half the watches in the delivery received are of the colours we ordered.Our Hong Kong agent assures us that she stressed to you the importance of following our instructions.Since we consider there to be only a limited market in this country for watches of other colours.Any watches that are not of the specified colours will , of course, be returned to you.   

We are also somewhat concerned about the rather poor quality of the goods received.since it is obvious that the watches that finally arrived have been produced from inferior materials and have been made to a lower standard than those in the sample.We have also found that a number of the watches do not appear to be functioning.We should like to point out that we feel this matter to be entirely your responsibility.

As a result of the above problems,therefore,we feel that the most suitable course of action is to return to you unpaid any of the goods considered unsatisfactory,and to deduct(扣除)any costs from our final settlement.We shall also be forced to reconsider whether any further orders should be placed with your company.

We look forward to your immediate reply.

Yours sincerely,

John Smith
