Fedex — Paid $300 for package to philippines that never arrived

I sent an extremely important fedex package to the philippines on 8/14 with a scheduled delivery of 8/23. On 8/23 the recipient received a text from fedex saying it had cleared customs and told him the amount for import taxes and told him to make sure he had the money ready. It is now 9/5 and i have called fedex numerous times but nobody knows anything and nobody ever gets back to me even though they say they will open a case to find the package. The tracking briefly said it foes not exist and now says subject to regulatory review. This is horrible service.
