The writer of the letter saw the advertisement over

Dear Sir,
    Just over six months ago, I saw an advertisement in the Morning Mail for a set of the complete works of William Shakespeare. Your company, Cosmo Books Ltd, offered this set at what was claimed to be a "remarkable" price :fifteen-pounds and fifty pence, including postage and packing. I had wanted a set of Shakespeare’s plays and poems for some time, and these books, in red imitation leather, looked particularly attractive; so I sent for them.
     Two weeks later, the books arrived, together with a set of works of Charles Dickens which I had not ordered, so I returned the Dickens books to you. with a check for the works of Shakespeare. Two more weeks passed. Then there arrived on my doorstep a second set of the works of Shakespeare, the same set of novels by Dickens and a set of the plays of Moliere, in French. Since I do not read French, these were of no use to me at all. However, I could not afford to post all these books back to you, so I wrote to you at the end of August of last year, instructing you to come and collect all the books that I did not want, and asking you not to send any other books until further notice.
     You did not reply to that letter. Instead you sent me a bill for forty-two pounds, and a set of the plays of Schiller, in German. Since then, a new set of books of different authors has arrived every two weeks. The books are still all in their boxes, in the garage, and my car has to stand in the rain outside.
     Please send no more books, send no more bills, send no more angry letters demanding payment. Just send one large lorry and take all the books away, leaving me only with the one set of the complete works of Shakespeare for which I have paid.
                                                              Yours faithfully,
                                                               Simon Walker
