Dear ———– [Name],
Instead of ————- [Requested Products / item], we have received a shipment on ——— [Date] of ————– [Shipment of products]. Enclosed, pleased find —————- [Supporting document enclosed], a copy of our P.O. # —————] confirming our order.
Please check your records to determine whether I am mistaken or not.
Unfortunately, I must request that our order be canceled. The time required to re-ship our order will significantly delay our schedule. Accordingly, we have arranged for our —————- (clients) to provide the ————- (products) through their suppliers. Your trucks have taken the original shipment back to your premises.
I regret that we were unable to complete the order. As I am certain this is an isolated incident, however, I look forward to continued business with you in the future.
Sincerely,
