Faulty TV replacement and poor communication from the branch managers

Early this year I complained to Game about my faulty TV i bought at Reeds Mall in Centurion, I returned the TV as they requested for assessment and I had to keep on calling them for months until they replaced my tv. Still the "brand New" TV they gave me is faulty........the remote is not working and manual buttons only volume and power buttons works. I emailed the 2 branch managers that i have been interacting with previously and both Amos and Celine are ignoring my messages.
