Terrible service from DHL Express South Africa
I opened a DHL Account and did only one shipment (which was a mess altogether until it's very late arrival) for-which I paid DHL for the not-so good service. After paying my dues IN FULL, 2 weeks later I kept getting emails that I owed DHL. Despite confirming having paid and sending proof of payments the emails kept coming. I responded and requested for someone to phone me for a verbal discussion, despite putting my number, no-one phoned. 
DHL Express service is terrible to say the least. My next step of course is closing this account with this useless and highly overrated company.
