Horrible service at Russells

I bought several items at Russells Boksburg, the items were delivered on 15 Dec 2020, including a Hisense 58 inch TV. unfortunately I did not check my items before delivery team leave. When i swtiched on the TV, I discovered that it is faulty, it has black mark on it. Russells doesnt want to change the TV for me, and i havent had a proper update since December, they are just giving me a run around including customer service. The customer service is even worse, they are not helpful at all. :-( Now i am expected to pay for the items, I will not pay until the TV is changed - complaint No: ***
