Dear Sirs, Two weeks ago, I sent you an order for 45 copies of the ' Contemporary English' dictionary, (147) the importance of swift delivery. They should have arrived last week at the latest when the new semester was due to begin. I have received no acknowledgement of the order, nor have the dictionaries (148). Failure to receive them on time is causing serious inconvenience. I shall be glad if you look into this matter as soon as possible and let me know (149) they may be expected. (47)
