Samsung — No response to complaints

Address:

Gurgaon

I have a Double door Samsung Refrigerator.In March 2014 I complained about the cooling issue.After many a phone call the call centre assigned the job to a incompetent service centre.The technician filled excess gas and I was charged a hefty amount.After some days the water started leaking from the tray at the backside.I complained again to the Samsung call centre who sent another technician who told me that due to excess gas filling there is frosting problem, hence the leakage.Was it my fault that gas was filled up excessively? The same technician told me that I have to pay for fresh gas.I complained to the call centre who promised me they will send someone else.Another call from a different centre who again told me to pay, without them visiting my place.I complained again and was told that they will send somebody.
This is an extremely frustrating experience and I vow that I will never buy a Samsung product and start a campaign in social media not to buy a Samsung product due to poor quality and hopelessly pathetic service.
