Bharat Lpg Gas — Delay in delivery

Dear Sir

I am a Bharat Gas consumer, & my consumer ID is B19216 in Visakhapatnam.
I booked my gas on 28 Jan 2010, but still now it has not delivered. When I am asking for the delay, agency is using very rough language and daily he is telling that it will be delivered next day but still now it is not delivered.

My Agency Name & Address:
Subbaih Gas Agency
Bharat Gas distributor
Madhavdhara,
Visakhapatnam
