What are they doing?

I am an inhabitant of North Halisahar, Ctg. I got my national ID card in the month of August before Ramadan. I found some mistakes over there & gave it back for correction. After one month, I went for collecting my ID from the board office but I was told that it was yet not prepared.
After that day I went there three times spending my valuable time & I got the same results.
What are they doing in the name of correction?
