Makro Negligence

I bought a 58" Sinotec tv and it was delivered on the 30th of August, a month later the tv gave me problems and contacted the Makro technicians as it stated on the warranty letter received with the tv, the came and worked on the TV, then the tv started having problems connecting to the wifi, the technicians came back and changed the motherboard of the new tv, thirdly all the apps that came with the tv were totally removed and only left with Netflix and YouTube everything else stopped working, on top of that they brought back the tv with a broken power button coverd in black tapes!!

I called the call center the entire week with no assistance, a lady from Makro finally contacted and told me that the people from Sinotec have to collect the tv, Makro can't send people to collect it because they won't give me credit...The people from Sinotec called me once to confirm my address to fetch the tv but it's the second week and everytime I call, they state that there are no technicians available in my area to fetch the TV.

This whole process is really frustrating, I want my money back!
