i am writing to inform you that the goods we ordered from your company have not been supplied correctly. On 4 September 2015 we placed an order with your firm for 12000 ultra super long-life batteries. The consignment arrived yesterday but contained only 1200 batteries. This error put our firm in a difficult position, as we had to make emergency purchases to fulfill our commitment to all our customers. This caused us considerable inconvenience. i am writing to ask you to please make up the shortfall immediately and to ensure that errors do not happen again. otherwise, we may have to look elsewhere for our supplies. I look forward to hearing from you by return.
