Great Eastern Appliances — money refund

Address:

Kolkata, West Bengal, 700034

I bought a product from great eastern dalhousie branch kolkata. Bought an air conditioner. Unfortunately my product was replaced with the company and my product amount got low due to changes. I bought the product in 09.10.2018. Due to massive careless authorization i got my product delivered after one month, that on november. After that i visited many times went for the refund money, they responded me with refund mail still didn't departed yet. Now the month december still no refund email came to my news. I am calling the agent, they are not responding also. How careless and how great eastern incoming bad reputation easily i can watch it.
