PayPal.com PayPal PayPal - helping Scammers steal your money Internet

I sold an iPhone via ebay and the buyers requested their money back claiming they never received it. I provided a tracking number showing it was delivered, case closed right... no, Paypal still ruled in their favor and took the money out of my paypal account. immediately after, the buyer turned the phone on in their name. I provided that infromation to paypal, and have contacted them every day since... it has been almost 2 weeks and PayPal has not returned one message to me and continues to ignore, still not acting even though I have provided more than enough evidence to support my case. I had the phone blocked through at&t so it cannot be used and the users account has been suspended for using stolen hardware, I have even filed a police report in the county sherriff's office where the buyer lives, enough evidence for them, but not for PayPal, who to this day will not even return an email. Im out my phone and my money, PayPal took it from my account and it seems since they are a large company they are untouchable, I dont know what to do, but I am very upset and feel very violated.
