Fedex incompetence

I purchased two items on Ebay, they were sent with Fedex and arrived in South Africa on the 18th of November. I received an email from Fedex informing me that these items were stopped by customs and Fedex requested some documentation from me to assist with clearance. I sent the documentation. After sending I received no update. I contacted Fedex via email again (the only option as all of my phone calls were unanswered), they again requested the documents. I sent them again. No update and no delivery. I managed to e mail Fedex customer services. They requested the documents again. I sent them again. Still no feedback or delivery. Phone calls to Fedex reception are never answered. I have tried to call the direct lines of the Fedex staff who are meant to be assisting me ( these landline numbers appear on their e mail signatures). To date not one of them has ever answered their direct line. In 30 years of business I have never encountered such poor service or incompetence.
