Voltas — Window Air conditioner

My Air conditioner bought from Tata cliq of brand Voltas has been dead for over 2 weeks now. The service centre of Voltas has been useless they have visited my home twice more than a week ago but nothing happened. After chasing them up and calling several times I was told that condensor needs to be replaced but it is not available so I need to pay up depriciation amount to get a replacement. This all is happening when my AC is under comprehensive warranty for 5 years and I have also taken the yearly AMC as well and ac is not even 1 year and 3 months old. This was a defective product that was delivered and have raised atleast 10 complaints ever since I bought it. Details of product Voltas 1.5 Ton Copper (2020 Range) WAC 18H DZB (R32) Hot and Cold Window AC (White) 1.IMEI/Serial Num 4011359A20GC00520. Invoice attached as well. Either I need refund of Rs 28000 which I paid for the product or a replacement with similiar product without paying anything. What's the fun of buying something with comprehensive if Voltas is threatening me to pay up for depriciation.
