Samsung S7 repair fail

<p>My phone just failed a 4th Quality Control test with Samsung Mobile South Africa - I now genuinely believe that Samsung has destroyed my phone and are just refusing to admit this and give me a new one. What a horrific 8 week experience with ADH and my phone has been sent back to Nelspruit for the 4th time for what I anticipate will be a 5th failed repair. What's the point of a warranty again?</p> <p> </p> <p>Phone was handed in - in January for a screen repair. They have failed to fix my my phone properly and the back cover won't close. 4 times? rather replace the device and let's move on. Why is it being sent back for a 5 th time? surely the device is destroyed by now, hence it can't be fixed. </p>
