Terrible service provided

After patiently receiving my pre-ordered gold S6 Edge I started incurring issues eg my battery would be at 40% by 12pm (thus only 4 hours after being taken off charge) as well as touch screen issues (Not allowing me to swipe to answer calls). I didn't want to be dramatic and thus asked a few other S6 owners if they were incurring these issue before taking the phone back. After less than 3 weeks of owning the phone I decided these were unacceptable issues for a phone that costs over R15 000. I took it to Vodacom Sandton and was simply brushed off to just take it to the Vodacare upstairs and get it repaired. I was told this was a factory default and would take between 1-5 days to be repaired. It is currently day 6 and I am still using the loan phone (which is equivalent to a Nokia 3310). I don't see why I am suffering all these inconvenience after buying one of the most expensive phones on the market and the issues are factory defaults. I am not impressed at all!!!
