We had purchased haier refrigerator by 27 - december-2018, but after that we found that the colling process is very slow and as company is always declared that 1hr ice magic program also in feature but i never found it in. I had complained for it to haier and the engineer was visited to my place, as per him some gas issued he recognised in the same. But please explain why we accept this demage peace and why we need repairing to our new refrigerator... We actually need replacement for the same.
