I need help this is frustrating

Im not angry just frustrated. Long story short i need a solution cause i paid Dhl for the service. Some of my items got ****** and Dhl Za contacted Dhl Hong Kong for the claim process but now three weeks later nothing has been done yet still waiting for my refund to start ordering the missing items. My shipper would have been contacted by Dhl Hk still no communication i contacted Dhl Hk about this no communication back this is bad for such a big company. Please solve this issue asap. Dhl South Africa did communicate with Dhl Hk dont know if they received any communication back. My shipper asked for a case number but Dhl South Africa can only provide the waybill which apparently doesnt help as the case number. Please help i never been let down since using you for a couple years now.
