If that happens, PLEASE escalate it to Amazon.
Aramex has NO right to ask you for additional fees, Amazon has prepaid all fees.
Also If Aramex insists because "the paperwork is wrong", again escalate to Amazon, they will reimburse you and take it up with Aramex.
That isn't your battle to fight.
Sometimes Aramex has issues collecting people's IDs and they sent me a message the other day asking me to send them a bunch of things
I asked them for details so I could send it to Amazon, then suddenly my shipment moved ¯\_(ツ)_/¯
They have a huge contract with Amazon so there shouldn't be a bunch of extra process there.
EDIT: I remember now, they asked me for 3 months unredacted bank statement and I refused. I only gave them the part for the Amazon transaction. I said I'd like to take it up with Amazon and please link me to the legislation requiring the collection of that level of information. They never responded and just sent my stuff along.
^^ is true for all orders "shipped by Amazon"/"fulfilled by Amazon". The only time you are on your own are the super, super rare sellers that are "Shipped by <bla bla>" where bla bla is the seller's name. But it is pretty rare to find those these days.
