Samsung letting down South Africa

While their products are great their aftersales and service is pathetic. I bought a 60" SUHD tv last year and after 10 months there was signs of screen burn and a pink screen. It took me more than a month of begging and pleading with Samsung and MM All electronics to fetch my TV for repair. After being thrown pillar to post trying to sort out the pick of the TV (with MM all electronics) I had to deal with consultants dropping my call, consultants unable to find my TV, consultants telling me that they cannot do anything because the ticket is with MM All electronics, consultants from MM All telling me that they have no obligation to update to me?! At what point does Samsung say that their loyal customers are being let down? At what point does Samsung say that MM All electronics is letting Samsung and it's customers down? After numerous promises made via the call centre - I have still not received an update and neither do I know where my TV is or when it will be repaired.
