Stuck at customs due to payment problem

My personal package which should be delivered to me at my work address is stuck at customs since Fedex want to charge my employer the import duties but my employer’s account has a block on it.

The problem I have with Fedex: 1. The fees is my problem not my employers. 2. I paid for 1-2 business day delivery option and it now the 3rd day and this would have held up the process indefinitely if I hadn’t contacted Fedex since the tracking page said I should do nothing and quoting them “No action required at this time.” 3. The price I paid Fedex was almost R1000 for a R2000 item of 1.6kg. One would expect better service at this price. 4. There must be a better solution for me in order to get my packages quicker if I’m not a company. Why can companies get their packages immediately since if there wasn’t a block on my employer’s account I would have had my package by now…
