Q: Drained battery and unesponsive Iphone 5c HELP!!!

So I have an Iphone 5c which I got back in March of 2014. It has been lying dead for about a month without charger so the battery is completely drained. I have tried every method on the internet and nothing is working. I have held the home and power button for a minute and nothing happens (I did this so many times I can't even count them). I have charged it for hours using every WORKING charger I  own with still no luck. It won't connect to itunes on any of my computers and I won't respond to anything. So I can't restore it to it's factory settings because it wont connect to itunes. Also there is no Apple store in my town so I'm pretty stuck. Any suggestions?? (I really need some help here that is my ONLY phone)
