Bests & Worsts Reviews from Amazon

Some of my friends don't have my cell number, so I use the Facebook app to chat.....then it won't let me do that anymore, and this "messenger" program won't stop bugging me to download it....this is the stupidest and most rude thing I've had to deal with.....not only do I not have a computer,and have to use my kindle to go online (which is frustrating by itself) I'm forced to use this new app just to talk to my friends? This is madness.....and to top it off, the app sucks.
