I am appalled by the service that I have received from DHL South Africa

I am appalled by the service that I have received from DHL South Africa. I ordered a pair of shoes from GOAT, an online footwear reseller. On 30 July 2026, I received confirmation that DHL was in possession of my shipment. According to the payment information provided by DHL South Africa, DHL offers a seven-day facility for VAT and duty charges. Despite this, I made payment on 9 August 2026, and DHL subsequently provided me with proof of payment, which I still have in my possession. It is now 19 September 2026, and I have still not received my shoes. Since making payment, I have made numerous attempts to contact DHL's customer service department regarding the whereabouts of my shipment and the failure to deliver it. I have retained the call logs and other relevant documentation evidencing my attempts to resolve this matter. Despite these repeated attempts, my matter has neither been properly attended to nor resolved.
