Acknowledging receipt of an order
Dear Mr. Ian,
We received your order (No.12345) for various building materials and we shall be dispatching them to you soon.
The smaller items will be sent by the usual lorry transport. The steel cables require a special trailer to transport them. We can only secure the services of such a trailer at the end of this month, so there would be slight delay in delivering them to you. We apologize for this unavoidable delay.
