Another Samsung Galaxy S6 Fails

Vodacom replaced my Samsung Galaxy S6 on 12 February 2016 after replacing one part after the other in an attempt to fix it. The device would not boot up. At the time I asked them if there was a known quality issue with the S6, because if so, I would prefer to change to a different device. They did not say anything, but gave me a new S6, so I assumed that it was only my device that was a dud.<br> Now, 6 weeks later, the second S6 has packed up. This morning it was dead and would not start up. It displays 0% battery level despite having been charged. When connected to a charger, it does nothing. Tried different chargers, laptop USB connections etc, no luck. It is dead.<br> Clearly there is a problem and Vodacom / Samsung needs to admit it. Using an Android based phone is critical to my work, so I am completely *****ed, again. I need the phone replaced with something that will work and keep working.
