Address:

god knows

For shipment [protected] aramex is trying to charge me the prepaid customs, taxes and duties again, i have shared the the invoice of my purchase where it's clearly mentioned that i have already paid for shipping, duties and taxes, whereas their customer care representative told clearly that it's none of their business if i have paid the duties, taxes and customs they haven;t received it, when i told them to contact(fenty beuty-from where i ordered the item) regarding this matter, they clearly denied saying that it's none of their issues, so i want to know one thing if you are the medium between the company and the consumer then who will be responsible for it? and it shows how this organization cares about it's customer.
