Shocking service Samsung South Africa

Purchased a new 75 inch Samsung TV from Makro. To make a long story short it started not coming on when switched on a few months after purchase. I reported fault to Makro and they notified Samsung. The Samsung technician said the screen was faulty and then needed to repair it. I refused as this was a new TV and i wanted a replacement! 4 weeks later and i am still being messed around by Samsung and empty promises. People just dont call you back its like they couldn't care less. Extremely bad service from Samsung. Markro guys are trying to assist me to get a replacement but they also are getting bad service from Samsung! From my personal experience, after sales service is non existent from Samsung. Pointless purchasing their products if something goes wrong and you are left to your own devices!! The worst service i have ever received from any company in my life!
