FedEx South Africa - Utter incompetence.

I have previously ordered items from a company in the US , this time I opted for priority courier service, the shipping went well until it arrived in South Africa , and is now stuck at customs. Due to negligence by FedEx and not fulfilling their stated services on their website , not following up with the shipper for the correct paperwork/codes etc. This reeks of incompetence. Calls don’t get answered, emails get returned due to “inbox full” , when someone does call they are rude and dismissive, not interested in a resolution. Complaints on the website get ignored. Instead I get sent a one line email response containing a code without an explanation of what to do, including a disclaimer stating that I will be fined R.5000 if the item isn’t cleared within 7 days. I have repeatedly stated that I am not a commercial vendor but a private individual. All for personal use. Someone isn’t doing their job.
