Services are bad. Review on Godrej 260 L Frost Free Double Door Refrigerator (RT EON 260 P 2.4)

I have purchased godrej frost free double door 331 liter fridge in 2 months it starts giving sound like generator we had launched a complain to customer care their technician came and did something with fridge again after a month it started giving sound like a bullet bike again we called customer care this process happened for five times then we said to replace the fridge because there can be some major problem and it is under warranty so why we should go ahead with a defected fridge we had to bear that sound regularly for one week then replacement came we opened new fridge some parts were missing still we keep launching complain to customer care so 1 by one parts are coming still not got full parts so my doubt is that how it is a new fridge some parts are missing means it is not coming directly from factory because if it is coming directly means it will be proper fitted so do not know what is going on.
