Consumer Redressal

This is to bring to your notice a mal practice among Television dealers (my case Sales Emporium,Ultodanga,Kolkata) I just Bought a Sony 32 inch and a LG 26 inch TV- To my surprise I found the LG TV BOX serial number and mfg dates are diffrent to the TV details and the TV did not quite seem new. They either have provided the Demo set or an old self-used set. They have changed the set immediately after I asked for the reason of this (I have taken photoes of the serial number as proof) but not many people would compare the box and TV dates like this ! I would request you to take necessary stringent steps.As this might happen to any customer or any brand hampering interest of both! Customers dont get what they deserve and the brands need to provide warranty on a used/demo set. I am raising this with all major companies and Consumer forum in West Bengal.As a valid customer I should get a New Sealed Set. Please help me fight this corruption!
