6 Weeks and still not repaired

I received my new Samsung S6 Edge end of May 2015 and it stopped receiving 4G signal and also constantly dropped calls on 18 June 2015.<br> <br> I went to the Samsung Smart Care Centre in Constantia Business Park and was told that although the phone is only a couple weeks old they will have to repair and cannot replace. Service agent mentioned they only have one tech trained on the S6 \because it's still new". I handed the phone in and received it back a week later"
