Consumer Redressal

I brought Sumsung TV from Oman on 23-05-2013. I got world wide warranty of the said TV for one year. I lost bill of the said TV at the time of my house shifting. So now I don\'t have the bill of said TV. Now the said Tv is also not working. It occur some problem. I do complaint in Samsung service center and they send an engineer at my place. He refuse my TV warranty as well as to repair the said TV on the basis of I don\'t have bill. But I am registered owner of the said TV. My name and address was already with them. Its shows I am Registered owner. Then too Samsung refuses to give me warranty. I can not afford expenses of repairing. Except bill I have all the Documents of the said TV. Then too I didn\'t get warranty. Please help and guide me as early as possible.
