An apology for errors on order

AN APOLOGY FOR ERRORS ON ORDER

Mr [CONTACT name],
When [the company] makes a mistake in a command, we are always a serious matter. Given the circumstances, your letter was a special brand of patience and understanding. I must confess that I'm more than embarrassed by this incident.

Let me summarize the errors:

1. A delivery you has been requested for [DATE], but have received the order as [DATE].
2. [EXPLAIN OTHER ERRORS]
3. [EXPLAIN OTHER ERRORS]

Excuse the repetition, but should I present the facts as they occurred.

I have trouble understanding how such errors could be committed. We can barely imagine these three errors and the President of [the company] is also embarrassed than me. When I got on the phone, I could get the promise that a delivery of [DATE] date will be marked on orders, while insisting on the fact that if there were still new errors, we would go elsewhere for our next orders.

Receive, dear Sir/Madam, my best regards.

The Director-General
