help

Hi in December I upgraded my phone to icon2 what a big mistake that was. About a month or two I had to send my phone back because I was having many problems with it. Now my problem has turned in to a  disaster to the point I can't even open and play a game.Please help when I try to open an app it closes right away. When I try to open my cricket app it also closes. A box keeps popping up saying cricket is trying to stop and close app. This started happening when my phone installed new software update. I can't even play a game. It's obvious this phone ICON2 ISNT working and no matter what in settings a cricket representative tells me to do it isn't working. I have had many problems with cricket and I say to the Representatives that I'm going to change providers. Cricket doesn't try to keep there customers they say right away ok want us to cut your service off now? I can't do anything on my phone if you can help great, This time I really think I'm going to have to go with did different company. I have been with cricket for 11 years that's a long time and for cricket not try to keep there customers is a shame. I guess they make so much money they don't need customers that's been with them for 11 years. My screen name is brokenup59@gmail.com my name is Robin
