Game Mall of the South not willing to book or repair my TV because it is "Too big."

Bought a Hisense TV from Game Mall of the South. The TV stopped turning on so I took the tv off its mountings, boxed it up neatly in all original packaging, loaded it in my vehicle, went through the process of getting to the mall and fitting it on a trolley etc. Just to be told that Game isn't willing to book my TV because it is too big. The Customer care agents are lazy and unwilling to help whatsoever. Threw away my slip in the process of making copies and just ignored any and all of my questions. Terrible after sales service. Now I have to try and get the manufacturer out myself on a product BOUGHT FROM GAME that is STILL UNDER WARRANTY!
