Order cancelled and sale lost – Courier ignored my reschedule request

I am writing this to express my absolute frustration with The Courier Guy. I had an order (Waybill: FDGTFP) that I specifically rescheduled using your official channels. I have proof of this confirmation. Despite my reschedule, the driver/depot completely ignored the instruction and initiated a "Return to Sender" (RTS) without ever consulting me. The package has now arrived back at the sender. Because of this gross incompetence and the resulting delays, I no longer need the package and have had to cancel my order entirely. Your failure to follow a simple system instruction has resulted in a lost sale for the sender and a massive inconvenience for me. I expect a response explaining why your rescheduling system exists if your depots choose to ignore it. Waybill Number: FDGTFP Location: 534 Rev EJ Motau Street Kudube unit 1 Temba
