Dear Mr. Santos,
First of all, I’d like to apologize for the mix-up with your company’s order yesterday.As I understand it, you received 10 ink cartridges fewer than you requested and an additional box of printer paper, as well.
At GMO, we pride ourselves on our attention to detail, so I immediately began an investigation. It turns out that a member of the administration team caused the problem. He confused your order with that of another firm with a similar name, Hillman Finance. This sort of mistake is unacceptable, and I have given that employee an official warning about his performance. I can assure you that all staff members will take the utmost care to ensure your order is processed correctly in future.
The good news is that the correct shipment is now on its way. It should arrive sometime tomorrow afternoon. Please make sure a company representative is on hand to sign the delivery invoice at that time.
I understand that our error has caused your firm significant distress, since you are now running low on stationery supplies.As compensation, I am willing to offer a 30% rebate on this order, as well as a $50 credit on your next order with us. I hope that these terms are satisfactory.
Regards,
Gemma Hutchison — GMO
