People who live in the Philippines...I need help ASAP!

Or anyone for that matter.

So, I made my very first sale on eBay! Yay me right?! Well it turned out to be a scam as I suspected. The buyer with the username "imbrenstemig" contacted me and told me he/she would like to purchase the item. After giving info about shipping and all that he/she used the "buy it now" feature. I noticed he/she had zero feedback and I was thinking maybe she was just a new user. So I thought using paypal was safe... this person paid me with a total different name and email address, and I was thinking maybe it was her bf/husband (because sometimes I use my bf's account) but at the back of my mind I already was thinking it was something I should be alarmed about. The person im having these email conversations with has a different name from the person it was sent to and the person who paid. I'm pretty much fucked because I am not covered by Paypal's seller protection plan. To be covered I would have to have sent it to a "verified shipping address" and (not or) have to have proof that it was delivered. The proof of the delivery part is probably okay because I shipped with USPS Express Mail with insurance and they would have to get a signature but the other part is what I am kicking myself in the ass for and that I should have been more careful... They buyer didnt have a verified shipping address. I tried contacting USPS to have them stop the delivery but they cant do anything because it has already reached the Philippines and USPS can only recall a package or do anything with the package basically is if its still in US possesion... What I am trying to do now is contact Philippines customs or The post office (the package is being delivered in Pasay City) so I can have them stop from delivery! I've been searching HI & LOW for contact numbers and I am trying to do all this before it gets delivered. It has been in P.I. Customs possesion since the 14th...They could be releasing it very soon. And once it delivers I have no choice but the refund because the credit card holder made a complaint that they didnt authorize the charge... and If the item was worth let's say $100 -$200 I wouldnt be as worried...but this item is worth $700. This person is a true scam artist!
