Extremely disappointed with the service received from CourierIT / RTT Group

Extremely disappointed with the service received from CourierIT / RTT Group. I missed the delivery driver today and immediately contacted the WhatsApp support chat at approximately 12:15 PM requesting assistance and asking them to contact the driver so he could return. I was then redirected to RTT Group, yet hours later I still have not received any response or assistance whatsoever. This level of customer service is unacceptable. When customers make immediate contact and actively try to resolve a missed delivery, there should at least be communication or feedback from the support team. What is even more frustrating is the complete lack of urgency and accountability shown after my request was made. Customers should not be ignored after reaching out through official support channels. Urgent intervention and feedback regarding this matter is required, as this experience has been extremely disappointing.
