This department store never gives receipt for any product purchased. They are cheating Income Tax department a lot and there is no one who is complaining about these guys. When I asked for a receipt/bill for my purchased products, they gave me a blank paper and wrote the amount on the paper, when asked for the pakka bill, they just put a stamp of their firm and handed over the simple blank paper to me (mentioning the amount of the products) saying that this is the ONLY bill they have and they don't practice giving any bills for the products purchased if at all I want to buy any product from them.
I request the authorities/ IT department to look into their dealings and help the country in preventing corruption.
