Samsung S6 Edge

I logged the following query with Samsung services on the 25/06/2015.<br> <br> I upgraded my phone to theS6 Edge in April on release day in South - Africa.<br> <br> I use to have the S3 and then S4 and now the S6 Edge.<br> <br> But at this stage I am NOT happy. <br> <br> 1. The phone hardly ever has proper signal. People phone me and the phone goes to voice mail and this happens in areas with very good signal quality. And these areas I previously had no signal issues. My whatsapp messages comes through 4 hours later.<br> 2. The battery life on the phone is about 4-5 hours with minimal use.<br> 3. The phone is overheating.<br> <br> After this I only got a SMS and an email saying a called has been logged but no one from Samsung has contacted me. Seems once they have you as a customer they don't care about service.
