My iphone 5s will not turn on. Hard reset doesn't work and itunes doesn't recognise it

My phone hasn't turned on in 5 days. Doesn't respond to the charger or being plugged into the computer. I've tried the hard reset a thousand times and nothing happens. ITunes won't recognize my phone so I can't do a factory reset. Can anyone tell me another way of resetting my phone?

I KNOW WHAT HAPENED!

Its the exact same with my phone. Mine has been off for 3 days and i can't find any way to fix it

IPhone 5s won't turn on unless charged and even then it won't let me get on my phone normally and keeps flashing logo with a low battery signal and a all red screen, occasionally my phone shows a iTunes reset. :/
