ARAMEX DOES NOT KNOW HOW TO TREAT A CUSTOMER

My parcel arrived in South Africa from Hong Kong on the 18th of December. 22nd of December I followed up and some information was taken from me. Today I called and no one is answering the call in the Customs and Clearance department. I am so irritated with them at the moment as it takes for ever to get through and the promised time lines are not been adhered to. Best part, I have paid for my parcel already. DO NOT OVER PROMISE AND UNDER DELIVER. ARAMEX DOES NOT KNOW HOW TO TREAT A CUSTOMER
