Why won tmy iPod Touch turn back on?

a few weeks ago i tried eeasing all data and content on my itouch in my settings and it said it could take up to 4 hours and i clicked ok and it took about an hour and it was fully charged and since then it never turned back on what do i need to do i really need it working again asap so please get back to me quickly. i connect it so it can charge because everytime i try to turn it on it says its dead and when it says its charged so that it can power on atleast it shows the apple logo and after a while it has like a thin line on over the apple logo and on the apple logo(still trying to turn on) it has a spinning wheel like the one on the top left corner when something is loading, but its on the logo and ive tried letting it try to turn 100% on by leaving it charged and powered on. ive also tried to hold the top power button and home button to 'restart it" but still nothing :c PLEASE HELP
