Disappointed with Makro Centurion and Samsung

I purchased a Samsung QLED 65inch curved LED TV from Makro Centurion on the 24 Nov 2017 - Black Friday deal. What i thought would be my dream TV has ended up being an absolute nightmare - just over a month later. On the 1st January 2018, a black line with a width of approximately 20cm appeared across the screen. I reported the TV to Makro Centurion on the 2nd and I was informed that a Samsung rep will call me with 72 hours to trouble shoot. After sending a tech to my house a week later - I was informed that Samsung will make direct contact with me. I eventually received a call from Riyaz from Samsung. He informed me that the TV could not be repaired. There were no replacement stock for the 7 series curved TV - hence they will ask Makro to return my purchase price and I could purchase another TV of my choice. Remember I purchased this TV at significantly discounted price on Black Friday or they can give me a flat screen TV and the difference there-of. I insisted that I either want this TV repaired or the equivalent. It was not my fault that Samsung disconitinued this series - a month after I purchased it. He confirmed that he could not help me further - Makro needs to resolve this wih me. Needless to say I had to call Makro Centurion. Pontso from Makro Centurion confirmed that she will discuss with her Merchandise Supervisor and revert. She called me a day later and gave me the same options. I explained to her that there was a specific reason I purchased the curved QLED TV - if the TV did not go faulty within the 1st month of purchasing it - I would still have a 65 inch curved QLED TV. I then had a further call from a Sharon at Makro Centurion - giving me the same options. Makro Centurion what dont you understand - I purchased a Samsung Curved 65 inch QLED TV - the latest technology with a 24 month Warranty - it went faulty within the first month. Please repair this TV or give me the equivalent!
