RTMC paying online for vehicle disc

Paid onlime for my license disc on 11 October 2023. The conditions state that delivery will be between 3-5 working days. It is 14 working days later and still no disc. Whatsapp no feedback received and call centre unable to get through. I sent an e-mail 4 times and only received respone once of screen shot of waybill no with skynet. No tracking update on the waybill track and trace since they received the parcel on 12 October. Why should I follow up with skynet if they are the service provider for RTMC? RTMC should abide by their agreement and assist their customers by followig up with skynet. This is unacceptable and very poor service.
