     Your twelve thousand 'Smart' watches were 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 regard to this order.

     It was firmly pointed out from the beginning that the delivery date had to be less than six weeks

from the original order in order to satisfy our own customers' requirements. While we understand tha

t 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 of its simplicity, and that your

existing stocks were sufficiently high to ensure immediate shipment. Late delivery of the goods has

caused us to disappoint several of our most valued customers, and will have an unfavorable effect on

future orders.

     The second complaint concerns the difference in colour between the watches we ordered and those

delivered. It was stated clearly in the order that watches in combinations of green/purple and orange/

purple only were required. However, only half the watches in the delivery received are of the colours

specified. Our Hong Kong agent informed you of the importance of following our instructions exactly,

since we consider there to be only a limited market in this country for watches of other colors at the

present time. 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 made from not good enough materials and have

been produced to a lower standard than those in the sample. We have also found that a number of the

watches do not appear to be working. Whether the latter problem is due to poor production, or damage

in transportation is not yet clear, but we should like to point out that we feel this matter to be entirely

your fault.

     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. We shall also, of course, be forced

to reconsider whether any further orders should be placed with your company.

     We look forward to your early reply.

                                                                                                                       Yours sincerely,

                                                                                                                              John Smith
