Who I have the same questioned this topic

I have a major problem with the new software update. Before my phone was working great. I could recieve text messages phone calls and all other notifications. I had my phone replaced 4 times and something is wrong with software update! Im stuck with a phone that doesnt work. Im wondering what are my options are because im very angry! Why would you allow a software update if its causing so many problems. Mind you THIS ISSUE HAS BEEN GOING ON FOR A MONTH AND MY PHONE STILL DONT WORK!
