Haier India Deep Freezer — gas leakage

I bought a double door refrigerator hrf2683 from nandilath electronics, nandilath tower, main road ottapalam, palakkad. When i bought it to home it had a gassy smell in the whole refrigerator. So suddenly we called to the service center of the company and the service man came and told that there is no problem in it after complete checkup (They can't recognize the gas leakage) and this complaint repeated for continuous 3 years so after getting fed-up we send it to the manufacturing unit where we able to know that it has a manufacturing defect... We filled the gas 3 times in 3 years.
So plz take tough decision while purchasing this companies product...
