Conn's Home Plus misled me in order to make a sell of a Samsung 4k Curve TV Webster Texas

My wife & I purchased a 55" 4k Samsung Curved smart TV from Conn's Home Plus. In the show room-picture was wonderful-very vivid, like you could just touch everything. When I installed the TV on the wall-adjusted the TV it did not have the same picture as in the show room. Call for a technician to . Monday 12/15/2014-technician Anthony stated that we would never have the picture as in the show room-that was like a DVD-the networkcome out-Directv-Comcast-ATT does not have 4k service-it would be months or years until they get it. We were not told about this service. My wife stated she wanted the same picture that they have in the show room-salesman said great that we would be happy. We are not-why buy a 4k TV when you can not get 4k service. Now they want to charge me 15% restocking-even though the salesman never explained about the 4k & that you have to have 4k service to have that kind of picture. We were misled to in order to sell us the TV. I do feel that I should not have to pay a restocking fee of any kind & that If I desire to exchange the 4k for another model with any penalties. This is not right for any company to do this to a customer. The sales person should of asked if I knew about 4k & that I needed the 4k service. The service tech explained that he has had numerous complaints from customers about the same issue-fantastic picture in show room, no 4k @ home only 1080p. Totally misled us...

All I want is to exchange the Samsung 4k Curved Smart TV no# UN55HU7250 for $1299.99 for the Samsung LED Smart TV no#UNH6350 for $1299.99---no restocking fee or penalties of any kind. Just exchange the evenly--same financing & 1 year no interest. All the same just the Samsung LED TV instead of the Samsung 4k Curved.               Again---no restocking fees or penalties of any kind.....
