Dear Sir.
May I draw your kind attention to my order dated 15. 04. 2019. Three months have passed since I requested you to send some books to my address at an early date. I regret to inform you that those books have not reached me yet. This delay has caused me great difficulties and some loss too. I had to procure those books from another source. So please consider the order as canceled if the books have not been already despatched.
Yours faithfully,
Mainuddin Ahad
