Dear Sir/ Ma'am, I am writing to you to inquire about the government job application which has been submitted to your department on 12th June 2020 wide application number HR/2020/12/07. It's been a long time since awaiting. However, I have applied for this post as a death case of my father. Since I am trying to get on the job on his behalf as I am the eldest person after his death in my home. I have four members in my family include me. My younger sisters are still unmarried and suffering from a lack of education due to financial issue. Hence, I am in a miserable condition. Therefore, I have completed the all process even though resubmitted the documents as requested. Last month, I received a letter for police verification which was also done appropriately in less time. Still, I did not get any information from your side. I want to request you to respond to the requisition. I will be grateful for your positive respnse. It shall really help me to improve my family condition. Thanks
