Samsung — Faulty piece of refrigerator of Samsung company

Sir / Mam, I m Hitendra Pandey from Bardoli (Surat). I had purchased a refrigerator of Samsung company. It's side by side refrigerator with the coast of 75000 Rs.. Just from the very first day of my purchase I saw a bunch of ants get an access to the refrigerator and throws a good amount of waste powder into the food kept in the refrigerator... I complaint to the shop and in return he complaint to the company executive... But the company executive answered in a very rough tone and said u apply some poisonous substance around the refrigerator so that ant won't come... But I m totally against of any such poisonous substance and acid to be kept in my home because once we had a horrible experience with this with our kid... I said them to replace the piece or refund the amount but they denied in either case... When I said them that I will do as per their guidance if they can give me in writing on that also they denied. Looking for a favorable reply... My contact no. [protected] Thanks...
