Flipkart — Product tv unit not delivered

We had ordered a tv entertainment unit from flipkart perfect homes sirens on 18th of October on hdfc debit emi basis, and product was supposed to be delivered on 22nd of October but as the delivery boy told the product is damaged during the transit and so he ll deliver fresh product within 2 days and also we called customer care and told the same thing. But still the product not delivered and we called customer care more than 100 times but they are negotiating the issue not trying to give resolution. Even we asked fir the cancellation but they are not doing that also. Since our money is stuck I want the fresh product to be delivered or I want the refund as soon as possible.
