Worst Service

The is my third complaint now and i wont stop until this matter gets resolved. As a small business owner for me the parcels that went missing was a big lost. Somehow Dhl South Africa keeps telling me the claim must be processed by Dhl Hong Kong two months later no feedback even on the claim. I thought Dhl must go out of their way for as a loyal customer to solve this problem. They dont really care about their customers. I expected Dhl SA to atleast put in more effort to help me solve this. And when ever i complain here they apologise but nothing is ever done with this matter. When i ask them a question via email they dont even reply back like a whatever mentality Dhl Hks problem not ours. From the best company in the past to the worst.
