Dear Sirs, I’m writing to tell you that your latest shipment ( 装运 ) of apples is not up to the standard we expected from you. Many of them are bruised ( 擦伤 ), and more than half are covered with little spots. They are classed as Grade A, but I think there must have been some mistake, as they are definitely not Grade A apples. We have always been satisfied with the quality of your produce ( 农产品 ), which makes this case all the more puzzling. I would be grateful if you could look into the matter. We would be happy to keep the apples and try to sell them at a reduced price, but in that case we would obviously need a credit ( 部分退款 ) from you. Alternatively, you could collect them and replace them with apples of the right quality. Would you please phone me to let me know how you want to handle it? Yours faithfully, Fiona Stockton Fiona Stockto n Purchasing Manager
