5th iPhone in 5 months !!!

Seriously trying to keep calm over the issues I'm having with the new iphone 5 !! I am currently on my 4th iPhone 5 in less than 5 months and awaiting my 5th which I'm seriously considering putting straight on eBay!! The 1st phone I had the on off button packed in! The second iphone I had the battery life lasted me 4 hrs! The 3rd phone kept freezing and turning off! The 4th has decided to come up with the no service logo and yes I have tried everything under the sun to fix this but was told it was an issue with the phones software!! For the love of god what is going on with these phones?? I've loved apple products and own a few devises but seriously had enough now looks like you'll be losing a customer in the next few days I'm afraid ! :(
