I dropped my iphone 5c and it went black but I can still hear noises coming from my phone?

I dropped my iphone 5c and the screen went black after a few minutes. My warranty is good for another week so i took it to team mobile to see how much it would cost to fix, they said it would COST $350 TO FIX IT.
I DON't HAVE THAT KIND OF MONEY TO SPEND ON MY PHONE. I still have apple care too. Should it cost that much money? And if not how much should it cost. What do i do? And if it does cost that much money how do i come up with the money in a week.
