Overnight Express not very overnight nor very express

Terrible service. Paid for Overnight express. (Item was coming from Pietermaritzburg to Durban). Item was collected yesterday 2nd December 2024. Delivery date 3rd December 2024. Called endless times to customer service and over the WhatsApp chat but to no avail. Kept saying it will be delivered. I waited at delivery location till 5:30 PM (place closes at 5PM) and still nothing. Kept saying driver will contact but nothing. Extremely disappointing. Durban Depot takes very very long to answer the phone. WhatsApp chat does not provide any useful information.
