CSD Canteen — dislike liquors variety forcefully issued to customers

Address: Thanjavur, Tamil Nadu

I am a defence costumer of csd thanjavur (Tn). There's a usual practice at the above canteen that high priced and brand liquor such as whisky, brandy are being forcebily issued to costumer against their will. When i asked to the manager about the practice, he told me that if you not willing to purchase you can complaint anywhere, since we are not bother it. I asked him for the complaint book, he refused. Please kindly look into the matter.
