FEDEX snail speed service

i paid over R1000 for a package to be delivered express. it is now over 3 months and my package has not been delivered. Fedex says its at customs, but seem to be doing nothing to ensure i receive my goods. i have made many calls, been refered from one agent to the next, i have been sent from pillar to post, spending an hour a day on calls, to no avail. poorest express service i have ever received, having been a FEDEX client for 6 years.
