From 5 stars to 1

I have a Samsung, I've had trouble with my phone.. Samsung fixed it.. quickly.. its been a great experience! ! I convinced my fiance to move from iPhone to Samsung. . Brand new 6 edge..so exciting.. After trying everything for 2 weeks, still no 4G. .. so sim swap.. but alas nothing... eventually he handed the phone in at Samsung Voda world on the 1st of June. ... to date he has not received a single message. .. call.. nothing. . He wants his iPhone back. Samsung.. please help me prove to him that I am not wrong and that Samsung is better than this!! Thank you.
