I regret to inform you that a letter of mine sent by speed post fifteen days ago, has not been delivered as yet. The letter was addressed to:
M/s Ankit Enterprises, 15/20, Gaurav Colony, New Delhi-21
This is a very urgent letter. Delay in its delivery has caused me tremendous loss both financially and mentally. Moreover, it has put me in an embarrassing situation.
I, therefore, request you to trace it immediately and expedite its delivery to the addressee. Otherwise, I shall be forced to take the matter to the higher authorities against you.
