Cocacola Company — Charged higher amount than the actual mrp

Address:

Ajmer, Rajasthan, 305001

Recently i went to a shopping mall, where i bought a bottle of sprite for refreshment. Later, when i asked for the bill, they asked me to pay rs. 22 for the product whose mrp is rs. 15. I asked the waiter to get me the bill for the product, which he bought after a long discussion with his manager.
In the bill, they refused to mention the actual name of the product, instead just wrote cold drink instead of specifying the actual name. I asked the waiter to get me the bill with the name of the actual product, but he refused.
Then i went to talk to the manager, where he accepted that they have updated their system with a higher price of the product and in addition, they have even added some tax. Even after a long discussion, he refused to give me the bill stating the actual name of the product, and also made me pay the amount they desired.
I am having the video recording of the entire conversation with the manager.
