Thank you for your fax of 16 July regarding the delay in delivery of your order for electronic components. I appreciate your bringing this matter to my attention.
I have checked the matter with our distribution officer who informed me that we have been experiencing a number of problems with the new transport company. I am afraid that the delay in delivery was due to their unreliability.
I really must apologize for the inconvenience you have been caused. I assure you of a more reliable delivery service in the future. Meanwhile, I can arrange for the overdue order to be delivered to your factory by messenger within two days.
If this arrangement is acceptable to you, please contact me as soon as possible
