Way bill number ***, Incompetence

Arletta Tshabalala has been handling my shipment which arrived in the country on the 3rd September 2015. She then contacted me & asked for my bank statement. I sent it through as she said she wanted to see the Amount payed when purchasing the item. Then asked for the invoice from my supplier. I sent it through then she through an invoice amount I had to pay from customs. I payed that invoice. After paying the invoice she went mute for over 7day up until I called to find out about the status of my shipment. She then emailed another invoice I had to pay including penalties of R2422.16 of which I payed as well. Since I have made that payment I have been trying to get hold of this Alertta person I call DHL approximately 5/7 times a day she does not pick up her line, the receptionist keep taking my messages and she never calls back. All I want from Dhl is to explain and tell me the way forward of my shipment and deliver it that's all I want. I have lost out on a month of business due to someone not doing their job. I will never do business with Dhl ever again cause of this bad customer service. I have used Dhl in the past year and this person Alertta has made me hate this courier.
