a lesson for life for everyone living in system , always mention name of the officer with rank requesting for any document, respond with matter attach desired copy and get it received manually stamped with date and diary number.
If & when same document is required again in same case you can submit the copy of that date time diary number letter as evidence, please locate in your records as it has been already submitted on so & so date
being part of system I know how deep we are corrupt bone marrow is just a material, our blood is seriously polluted.
( i mean no offence to anybody by any means )
