The Attic - Product is substandard with missing parts

I purchased a wooden bar cabinet online from the mentioned company (www.theattic.co.in) based out of Jodhpur and an employee named Swapnil Kabra was co-rdinating with me and he sent me the payment link and also proceeded the delivery. The company is also listed with online companies like Amazon, Flipkart, etc. The same product was also displayed in Amazon but was not available and also showing longer delivery time, so I went ahead and contacted the company directly for the product and they also asked me to buy from them directly and said they will deliver with * days. Now, the product came, not within * days but thats fine, and once I took the delivery and opened the product, I saw that the product does not look like shown in the photos and the finish is very substandard and also there are missing parts. I immediately contacted Swapnil and this is when he started to act tricky. He tried to pursue me to keep the product to which I denied and asked him to process a return immediately to which he was not ready. he asked me for some time and then stopped answering my calls. He replied to my message denying that its their fault and everything is fine according to him and he offered to change things in the unit by sending somebody which is absurd because its clearly not possible and even it has to be done it has to be taken to the factory. I have already lost trust in them and I just wanted to return the product. He told me that I will have to pay for packaging and shipping, which itself amounts to a lot if I have to do from my side. He is actually trying pressure tactic so that he can force down the worst product down my throat and get relieved of the responsibility. I have WhatsApp chats with him if required and also their website says that they will return/exchange the product under certain circumstances and more than one apply to my case. I have tried to get some grievance unit but with no result as I think they don't have one. I have stated posting on social media to get attention from some senior in their company if at all.But, the only other number provided on their website beside the employee Swapnil I was talking to, that phone keeps on ringing, without anyone answering. I am already repenting ordering from a random company but in my research they came across as a company who regularly sells on the above mentioned big online shopping platforms. please help. thanks.
