I actually asked for a re-assessment of customs fees before I paid. It was halved; but I should say that it was a hefty amount. The point here is that the AGS team allowed for re-assessment before payment.
There seems to be big delays all around. I have a package that hasn’t been scanned in by Aramex Hong Kong. A few others are quite slow to come from KL through Dubai as well.
I’ve had a package come into SA on 26/11 and be sent for customs clearance. But no movement since. AGS say they’ve escalated the matter but still nothing.
Happy to report that I have received two of my three packages with a minimum of fuss. They did however seem to charge me customs fees in USD. You live and you learn. But, based on my experience, I would definitely recommend Aramex Global Shopper.
