Lack of accountability

I purchased a Samsung 58TU7000 which was delivered on the 20th of Aug. To date the TV has been intermittently flickering white light and the only way to get it to stop is by switching the TV off and back on a few times. The TV isn't even a month old and clearly has a defect. I reached out takealot only to be informed that I must contact the supplier directly. I purchased the TV from takealot and expect to get service from them and not be pushed around to get this resolved. Furthermore they direct me the the supplier and say refer to details below but none is provided. I an not seeking a refund but a new replacement. Can someone please help
