DHL doesn't care about their customers

DOES DHL CARE ABOUT THEIR CUSTOMERS, I DON'T THINK SO !!! On the 28th of November 2018 some documents were send from The Netherlands to me in South Africa. The original tracing code was CY ********** 43DE. Only in the beginning of January 2019 the documents arrived in South Africa, tracking code was changed into EK ********** 65DE. When nothing happened I contacted DHL South Africa and was told that a parcel once arrived in SA, it would be handeled by SA Post (if I had knew this in advance, I would have NEVER used DHL, because one can't trust SA Post). I was advised to contact SA customer service which I did on the 3th, the 10th, the 23th and finally the 29th of January and received NO ANSWER at all. Because it remains the responsability of DHL, I contacted DHL SA again and got thia answer: Dear Jan I am afraid I do not have answers as I have been trying to get hold of the post office with no success for the past two days. There is no response from emails and I di not have their escalation point as that would help. Nosicelo Manentsa Customer Care Executive DHL ExpreSS I think this totally unacceptable, DHL has to take action and make sure that my documents will be delivered. Two months has already past !!!!!!!!!!!!!!!
