New iPhone 5 not charging when plugged in

I just bought a new iPhone 5, and plugged it into my wall socket. Apparently there was no charge. On the screen, the small lightning sign came up, which means its charging, however 7 hours later its still red and can't turn on.

Try another outlet, with chargers what I've bought from Walgreens (that didn't come with the phone), usually won't charge your phone if you push a lot on the cord- you could always take the phone & charger back to the place of purchase.
