Inefficient,frustrating and seriously appalling service by DHL

Dhl cape town customs department is highly inefficient with appalling customer service. 1st when shipment arrived in cape town and was held by their customs,no one bothered to notify me. I only found out myself when I called Thursday,they requested documents whuch I did provide. They made me pay customs and import duties but no progress,no feedback, everything stagnant except my frustration. They rarely answer their phones, they promise to call back but never do. Most times when theyeventually pick up phone,all of tgem they have generic/robotic response but when you need more info they get stuck. They have no sense of individual customer care/needs. I'm very disappointed and seriously frustrated, this is unacceptable that one has to go through hell after paying DHL for service delivery. Pleaseget my shipment to me asap this is unacceptable
