ShopCJ — no response and for paying extra money

I have mailed them so many times but they are least bothered about their customers. I have tried everything but they are expecting me to pay for delivery charges which is their responsibility. They anuja cse told me that inform shop cj if i m ordering my replace product that they will put the order on online payment so that i don't have to pay the delivery charges as information the complaint department told me so when i called them twice time for placing my order and informed them exactly what anuja told me they are rude and not listening anything and said that i have to pay 200 for the delivery charges. I said i m not going to pay any extra amount for their fault. Why i should i pay extra money when i had paid it already. Previously i have paid everything the product was defective after so much time they have provided me the coupon of 999/ with its expiry date instead of 1200. They are not replying my mails, neither solving my issue. This is not done i have paid it from my pocket not steal it from their bloody company. Already they have wasted my 7month till now i am suffering. It's their responsibilities to take my order without any charges and delivered it at my place and secondly they don't stick it with their given words. They are bloody # # and i am not going to tolerate anything and have no patience. They are not trust worthy at all and always keep fooling the customers. They are shameless and worst at providing services and it should be banned. Take some action against them. They are # chutiyaas because they understand this type of language only and harassing me from long time and the trauma which i am facing they will never understand it.
