Abysmal customer service from Game

Green Acres Game in Port Elizabeth has a very poor customer service. No one answers when you call and have tried calling the national game customer service line and the case has been escalated twice with promises of return calls from Game. We bought a Combo Samsung TV and soundboard. The soundboard stopped working well within the 2yr warranty on the receipt. Game says the problem is with Samsung and so we wait and wait and wait with no followup from anyone.
