The Courier Guy made me lose my customer and money in the process.

I been using the courier guy, Pudo service for quite some time now and up until today, ive been happy with it. On Tuesday 9 Dec 2025 I've deposited a parcel into the Pudo lockder. Ive noticed this morning (Friday 12th Dec 2025) that my parcel has still not been retrieved from the locker and after calling customer support service, they informed me that they would sort out the issue. A follow up call was also promised but up until now nothing. The customer that bought this item from me, now no longer wants it, as he has been waiting on it for too long. Whats going on at the courier guy and howcome no one has done anything about this since it was in the locker on Tuesday already?? I've refunded the customer his money and now i need to get the item returned to me.
