No delivery

Ordered a part from them on Saturday 2 December 2017. Part was sent to me with their courier, Aramex, to me. I stay in Mthatha, Eastern Cape. After a long battle, I did get a waybill from them to track my parcel. According to tracking, parcel was in East London and selected for delivery on 6 December 2017. I phoned Aramex and they confirmed delivery for 6 December 2017. When I did not reciced my parcel, I try to contact the branch again, no answer. I contacted the supplier again and lodged a complaint. They came back to me and said that the parcel will be delivered on thursday, 7 December 2017. Thursday came and no parcel. I contacted Clive Naidoo, on email, and he said he is waiting for a answer. After 3 hours I tried to contact mr Naidoo again, to no vail. I paid nearly R600 for the part with delivery and got nothing to show. Is that service?
