Dear Mr. Jones:
　　We very much regret to learn form your letter of 2nd March that you are not satisfied with the dress materials supplied to your order No.9578
　　From what you say it seems possible that some mistakes has been made in our selection of the materials meant for you and we are arranging for our Mr. Yang to call on you later this week to compare the materials supplied with the samples form which your ordered them.
　　If it is found that our selection faulty, then you can most certainly rely on us to replace the materials. In any case, we are willing to take the materials back and, if we can not supply what you want, to cancel your order, though do this reluctantly since we have no wish to lose your custom.
　　Sincerely,
