Haier India Deep Freezer — Refrigerator gas leakage

We had purchased 550 litre Refrigerator on 31.12.2020.

Just after one year of purchase, gas has leaked.

Reason advised is very silly that if there is drain in 3-4 Km, gas would leak.

If this reason is true, then refrigerator is not suited for cities as there is always a drain in 3-4 km in cities like Delhi.

True reason seems use of iron parts instead of copper.

As such, company should use better quality parts and also refill gas as free as this is more like manufacturing defect.
