Dear ___________________ (Name),

The purpose of writing this letter is to convey my apologies for the confusion that took place while delivering your order on ___________ (Date) corresponding to the order number ______________.

The whole confusion was caused due to the new packaging system that we have adopted which still has some flaws. The new order according to your demands has already been dispatched and probably you will receive it by the evening.

I deeply regret for the inconvenience caused to you in the whole process. We promise that the mistake would not be repeated on our part. To compensate for the trouble caused, we have enclosed the discount coupons for future purchase of our company products.

Sincerely,

Customer Service Manager
