Iphone 5 charger not working?

My Iphone 5 charger is not working. The main wire goes into the thicker part and if i pull the thinner wire/ main wire out 4 little wires are exposed green, black, red and white. If i tuck them in it still won't charge any help?

Its time to buy a new one. Stop being a cheap assx

Go to the apple store or amazon and spend $20 on a new lightning cable
