Haier - Repeated problems with refrigerator

I bought double doored Haier Refrigerator on **.*.** bill no **** from Jolly sales located at lower mall Patiala. It started giving problem in December ****. After repeated complaints and after about ** days of wait, * parts were changed named PCB for **** and fan motor for ****. I even connected a new stabilizer worth **** on their advice so that fluctuating voltage does not harm the functioning of the fridge. Now again the problem has started just after * months of replacing the parts. The technician from the service station of the company says that the fan motor has again stopped functioning and that part is not available with them at this time but they have to order it. Very strange. I had bought the most expensive fridge of a reputed company (that is I was told then) available in the showroom at the time of purchase but now it has become a nightmare for me. I m a working lady and whenever I have the fault with fridge I have to empty it and things get rotten. Kindly do the needful as I want my money back. Previously I had * fridges of LG and didn't have any problem for ** yrs and this company gives a warranty only for * yr and the fan motor has stopped functioning only after * months.
