Aramex, Nightmare Shipping company

I shop online locally n Globally all the time and I have never had a problem with any courier company. I find them efficient always, but for the first time my global seller used Aramex to ship my items n WoW, what a nightmare. First on my Friday I got an SMS requesting my ID no, same Friday I respond to the SMS via email with the requested information, I followed up on the email I sent on Friday only they say they updating the information, I follow up on Thursday because no one is saying anything to me. I will on hold for over 15 minutes going back n forth with the call center agents, Now I get a ridiculous invoice of R900 to pay for clearance for Goods for lesser amounts..Mind you I have already paid the shipping fee . I honestly have never experienced such a ridiculous service from any Company like Aramex.
