Game - Mall Of Africa

I have contacted Game at Mall Of Africa regarding the Optical Port on my Samsung 65inch TV which is only 4 months old and still under warranty which i think it's faulty . Upon that the guy tells me that I will be charged a call out fee if there's is nothing wrong with the optical port but the optical box that I bought is brand new and it's working on another TV .So since Game at the mall of Africa is not been very helpful regarding my problem so it's best I return the TV back which I will be getting reimbursed back my money and I will purchase the same TV from another . From yesterday mid day till now game store have not contacted me at all regarding the problem. Is this how game store at the mall of Africa treats their customer after purchasing a R13 0000 TV?
