What do I do with my IPhone 4S?

So i just bought a 4S at a Sprint store with a lifeproof case. Somehow water got in it and it won't charge anymore. Now if i want a phone I have to pay $200 for it?! Why? Its not my fault that the Case didn't work. I don't understand what i should do now, cause i'm getting screwed.

Burn it

Just pay 200

Call the company that made the case and tell them how poop their product is and tell them that it has damaged your mobile! And demand compensation!
