Dg Shipping — Issue of fresh chemical dc with only 1year validity.

Address:	Lucknow, Uttar Pradesh, 226017
Website:	mmd.gov.in

I have applied for fresh Chemical DC from Mmd Delhi and they provided me with only one year validity. I want to tell that last year also I applied same fresh Oil DC from Mumbai MMD and got validity for 5 years.
When I called mmd delhi they are not giving me any clarification specially man named DEEPAK and after that I again called and they put my call on hold as he is not present on his desk.
