Disgustingly poor service for courier service

I am so disappointed that I dropped off the parcel on the 36/12/2024 to be delivered in Bryanston till this date it's not delivered on the 1st day they attempted delivery I picked up the address was wrong and still they could not call to verify,they were just next to the correct address instead they returned and I was assured to get the delivery the next day.I once mentioned they did exceptionally well with a delivery...this is the worst service by far.I m running a small business and decided to buy 10 sleeves in advance I would really like a refund ,this is extremely unacceptable.They have failed me and my client and due to this I have lost a deal from the same customer that was going to pay R3000 for the next purchase. I need this to be fixed asap.
