My one start has nothing to do with Apple Store in...

My one start has nothing to do with Apple Store in Soho. This store was very helpful for the previous issues I had with my iPhone and my wife s and my father s. I m giving 1 star for the quality of Apple products especially for iPhones. I paid $800 for my iPhone 6 Plus and from they one me and my wife were having problems. Two days ago I did software update and now my phone freezes al the time and my battery dies in couple of hours. My father and my wife have the same issues. After changing the screen, due to Apple manufacture error, and having other issues with the phone now I have to worry about this new issue; battery dies. I was told I have to go to Apple store twice; first I have to go and let Apple Store to inspect my phone battery and than order it and two weeks later go back to the same store and wait for battery to install like I have nothing else to do. Quality of iPhones are far away from the price we re paying for the phones.By the way I have been trying to reach someone in Apple customer service but no luck!!!
