"Held in customs" for 3 weeks with no communication

Aramex requires that you send an invoice of your purchase for customs clearance. I uploaded it on their site, it shows that the document was attached to my profile, and a week later I received an update saying "held in customs - no invoice." I then emailed the invoice, and received a confirmation email "please be advised that your shipment ********** 905 will be submitted customs clearance, please allow 3-4 working days for shipment to release."

It is now a week and a half later since that email, and I've sent 3 emails to customer service since, with no reply. I called customer service this morning, only to be told that the invoice I had sent (from Paypal) was not sufficient as it did not contain a description of the items. After all this time, only now they tell me?! Absolutely shocking service. Will never use again.
