Dear Sirs

Dear Sirs,
Regarding the contract between us and your company and the order number 121 which was placed on the 23rd of December 2017.
We apologize for the inconvenience caused to you due to the delay in delivery of the order concerning the servers and network equipment. We have to inform you that this delay is out of our control as it is due to the delay of the export approvals from The Export and Import Control Authority. The Export and Import Control Authority are also flooded with a large number of unexpected approval requests with a limited number of employees inspecting the contracts and requests and all this has led to this delay.
We are trying our best with our legal team to minimize the delay as much as possible to reduce your troubles. We submitted a complaint to the authority regarding the approval delay and they informed us that they supported the inspection department with more number of staffs and by next week our approval shall be issued and within the coming week your shipment shall be dispatched for delivery.
You are a supportive client of our company since years, and we are grateful to you for your commitment towards us. As an apology we offer you 15% discount on your next purchase order with us. Whenever you place your next order, you can avail this discount on the final bill value. Once again we apologize to you for all the troubles caused because of us and we appreciate your support.
