Amazon refuses to give me a refund for the item lost?

I ordered an Iphone 6s from Amazon for 800$ it was "delivered" to me on Jan 20th. However i never received it the tracking number said that it was left by my door but i could not see anything. So I contacted Amazon and explained that i had not received it so it may have been lost or stolen they told me to contact the police and get a reference number which i did and i provided the reference number to amazon. Then amazon told me to wait because they will do some investigation and then finally 2 weeks later i call them and they tell me that they have contacted the post office and they have proof that it was delivered and its not amazons respnsibility to offer a refund at this time. I was so angry but she refused to provide further information.

What should i do?

Can I find a way to retrieve my iphone's pictures if it got ran over? (Doesn't turn on)?

Can I find a way to retrieve my iphone's pictures if it got ran over? (Doesn't turn on)?

Added (1). Recently my I dropped my iphone 5c in the school parking lot because I was late to school and it dropped out of my pocket while running into the school. I found it the next day in the parking lot smash and cracked and well it got ran over pretty badly. I'm pretty sure it got rained on too since it was raining that day. I was wondering if there was ANY possible way I could get the pictures from it because some of them are so incredibly special and precious to me. The phone does not turn on.

Can I plug one thing into two usb ports?

I just bought a Pioneer 4100NEX, which has two usb ports on the back. One of for Android Auto and the other is for Apple Carplay. I have both an iPhone for work, and a Galaxy (Android) as my personal phone. I use them both interchangeably, so I'd like to be able to use Carplay and Android Auto. I bought a port / extention that has one usb port and one Aux port. Is there an adapter or some other way I can connect that one usb to both ports on the back of the radio so I can use both Android Auto and Carplay out of the same port?

GarageBand (Most up-to-date version) panning/phaser problem? IPhone 5s?

Okay, so I'm trying to record a new song, and this is the first time I've ran into this problem. But I have an audio recording (2 actually) for acoustic guitar (no I-rig, just the mic from the phone) & the built-in drums they offer going through the verses. Just by themselves. But I have ran into the problem of all of those tracks lowering in volume tremendously, & then crescendoing back in high volume throughout the verse, & it works kind of like a phaser. And I'm NOT looking for that. It sounds like if you were to just turn down your volume on your phone in the middle of the song, & then back up. The thing is, I don't have any panning done to any of those tracks. No compression added. Just bass, and treble. NO panning at all, yet, there's panning? Bad. Can someone explain to me why this is, & maybe offer a solution?
