Samsung — Defective Samsung AC received and not responding when I raise complaint

I have purchased Samsung AC on 18th Mar 2021 and it got installed on next day by Samsung service team . After 2 days we found AC is not getting cooled and raised a request with Samsung support team. Next day they came and found complete Gas in AC compressor is gone and they refilled it. Not Sure why and how it gone. It worked fine for 1 week and later we had the same issue again. So on 31st Mar 2021 I again raised a complaint with samsung support team. But no one has contacted even after following up with Samsung support team daily. Even they said they have escalated to Service Head and he will contact you in 1 day. But no response from them. When i called on 12th Apr 2021, support team mentioned that they have closed the request as it was resolved. No body came and contacted me for repair but they have closed the request and followed so many times with them. Its been a month we brought new AC but sitting without use at home. I brought for sake of my small kid as its very hot in my place. Now i cant buy other one or use the defective product from Samsung. I am not able to contact any one apart from Samsung support team which is not resolving and do any thing about it, as i brought the product from Samsung online. I really want to take this to higher level and file a case on Samsung for sending defective products and not providing service for it. It may be simple issue but for middle class people it matters more when we buy high price product but its not working. As I and my Family facing issue because of the product we purchased from Samsung and no others should face such issues, so I want to file a case and they should pay high penalty, so they will not repeat such mistakes in future. Thanks and hope this forum will do needful for me.
