Poor Customer Service from Aramex

My parcel from the USA arrived in South Africa on the 04/08/2018 and has not been cleared by customs yet. Aramex South Africa is the courier responsible for getting my parcel to me. I am having a really hard time getting through to them by telephone as either no one answers the phone or I get transferred to someone who is supposed to help me but no one answers the phone. It is now the 13/08/2018 and no one from Aramex has given me any feedback regarding my parcel. This really poor service and a don`t give a damn attitude.
