Apple Store Gave My Prepaid Macbook Pro To A Thief And Apple Refuses To Refund Or Replace It

Can anyone who is a lawyer give me some advice?

I prepaid for a $5K MacBook Pro for pickup at the Americana Apple Store in Glendale. When I went to pickup the computer the Apple Store employee scanned my bar code without looking at ID and then casually told me the computer had been picked up. At first I was confused and told him it must be a mistake because I clearly wouldn’t be there if I had picked it up. He went to the back room for a long time and then returned and said the same thing. The manager then came out and told me the computer had been picked up and there was nothing they could do. I was shocked. I thought Apple was a premium brand with amazing products and security. How could they so easily be duped out of such and expensive product? In addition, how could this be legal? I never once touched the computer or had it in my possession, and yet they are pushing this problem onto me.

After leaving the store I did the following things:

1. Filed a police report (the officer said this happens all the time)
2. Called Apple. They said this has never happened (lie). They then said someone would follow up in 48 hours and they never did. (Lie #2). Last they said to file a dispute with my credit card.
3. Next I called my credit card to file a dispute. Unfortunately I put this laptop on the Apple Card. I got this card specifically to finance this computer since it was so expensive. My experience so far has been terrible. The employees can't give you any information and you can never get ahold of anyone that can actually help. From day one, I never felt like they had my back in this dispute since they are technically an Apple product.
4. After filing the dispute the charge was removed pending investigation.
5. After two months I recently got an email from Apple Card saying “Based on available information, we determined that the transaction was authorized.”
6. I call Apple Card to get more info. The first employee can only re-read the automated email to me. I ask to be transferred to the manager. I’m on hold for 20 mins and ask to be called back. I’m never called back.
7. I start a chat with an Apple customer service agent and explain all this. They escalate my story to a senior customer agent who will call me within 24 hours. I specifically ask to be called within certain hours so I can pickup. The agent of course, doesn’t call within those hours and leaves a voice mail saying Apple can’t help me and that i have to take this up with law enforcement and my credit card aka Apple.

Can someone help me or offer advice? How can this be legal? I never touched this computer. It was stolen from the Apple Store. Apple is refusing to give me what I paid for. Meanwhile I'm stuck with paying off this computer every month that I never received.
