A nightmare experience

I logged a return that was due to be collected on 7 April 2025. My runway and courier confirmed collection for this date and sent me details of the driver who will collect. 7th came and went with no contact from courier company. I contacted both my runway and the courier on 8th April and was assured that the collection will be scheduled for same day (8th). Again 8th came and went with no contact from Courier. I then requested my Runway to change my return option to a drop off at Postnet Glen marais. They confirmed this was changed and gave me a reference/waybill number. I received to different waybill numbers on the same day, one from Myrunway consulted Kira, and another from what appeared to be an automated Myrunway email. Both Waybill numbers could not be located on the system at Postnet. 3rd day lost of trying to return and item and get my refund.
