Samsung India — double doors refrigerator convertible

Address: Chinchwad, Pune, Maharashtra, 411033

Last i have purchased double door refrigerator samsung. On the day of demo and installation noise is observed. Samsung engineer and customer care told me to wait three to four months (No call recording available now i wonder why. Because in ever customer care call at start we hear saying call will be recorded) post four months that noise still persisted and i raised complaint again.. This time after two to three engineer vist finally they agreed it's a defect of compressor and changed it. (I could have raised request for replacement at the time of installation itself but samsung engineer misguided me and as it is my first refrigerator i did not know how it works). Now again cooling issue is observed. Ice is forming milk or any liquid we keep in fridge area and water is dripping from door. Raised complaint again and again engineer visited he cut paper foil from freezer compartment and stick it lower walls. Asked me observe for few days.. My question is why so many repairs needed for new refrigerator.. If so many repairs are needed then it means it is defective product but engineer not ready to listen itself.. What should i do.. I paid 26000 through emi to purchase it.. If that demo engineer and customer care executives did not misguided me i could have replaced it on that day itself.. What can i do now.. Samsung engineer saying replacement not possible only repairs.. Second hand fridge is better then buying new samsung fridge.
