Tablet Repair

In August 2014 I got myself a Samsung Tab 4. Since November 2014 the tablet started giving me problems. I took it to the nearest branch for help. They sent it to Tyger Valley Repair Center for repairs. It took them 3 weeks to repair the tablet. When I received it back still not 100%. I took it again to the nearest branch and again it took them near 3 weeks to repair and when I received it back they didn't even do something to the tablet, so here we go again for the repair center. This time they send it to the advanced repair center and took near 4 and a half weeks to get back. This time the nearest branch send me photos of the tablet it is not even assembled correctly. This Samsung Tab 4 is Cost me R 349 a month and for the last 3 months I had 1 weeks use of it.
