Amazon order still has not arrived and i've been charged. What should i do?

I ordered an iPhone from an amazon seller on the 19th of February. I paid £4.99 for delivery and the ETA was the 5th of March, although the package was not going abroad so I still thought that was a bit long but still waited. It is now the 15th of March and I still have not received anything despite being charged weeks ago. I contacted the seller and they said it had been lost in transit (they have the tracking number not me so I can't see the package status) they said they would send me another phone however its been a week since I last spoke to them and they are not replying to my messages anymore. What should i do? Thanks.

Wet iPhone 4s - covered with a Lifeproof Case already

My iPhone 4s is covered in a Lifeproof case. At my batch retreat yesterday, I wanted to take pictures underwater with my friends so I brought it with me to the pool. Little did I know that a little water went in, eventually, affecting my phone's function. I dried the phone; dried the "plug" part with tissue and even blowered it. The flash is lighted; even the vibrate button still worked but it didn't after a while. Now that I'm home from the retreat, I tried syncing it in iTunes and the only thing that pops out is the "charging" icon. It then turned into the Apple or the "restart" logo. Afterwards it turned black. Blank. Nothing.

Can somebody help me, please?
