Consumer Redressal

Dear Sir/Madam, I had bought a 40\" Samsung LCD from Next Retail with 2 years extended guaranty.The product has started giving complaint (Display problem)within a year.since it was in grantee therefore the screen were replaced. But after that the problem is erupting again and again. Since then it is got 3 times breakdown and the problem is always same (display problem). Same I had communicated to Next Retail, but they refused as the Samsung is \"OEM\", therefore ultimate responsibility is lying with Samsung for defective production. I escalate same matter to Samsung top team with end no of reminders to replace the LCD with similar specifications, but all in vain. I have the complete detail of mails sent to Next and Samsung. If required same would be shared with you. Kindly help me to replace the defective unit. Awaiting your swift action on it.
