Poor courier service

To date the worst courier service I've ever experienced. Wanting to send an urgent package of documents from Uitenhage to Bisho, they were recommended to me. Upon contacting them they had indicated that it would normally take 24hrs for such an overnight package, but as it was going to Bisho it would be necessitated to go via their East London branch. This would result in a delivery time of 48 to 72 hrs. I proceeded to drop the package at their collection counter on the Tues mid afternoon. By the Sat morning, when contacting the recipient to verify whether the parcel had arrived, I found it had not as yet. Utilizing the tracking number, I proceeded with an online query, only to discover that the parcel had arrived at the East London branch on the Thurs...and that it was still there! With their offices being closed over the weekend, I called their Port Elizabeth branch on the Monday, and a lady assured me that she will let East London (independent deliveries people) know to be sure to contact the recipient for delivery. On Tues I phoned PE brance again and the lady said she had eMailed East London, but couldn't phone out as she was working from home. She offered to give me the number for me to phone East London. I phoned the independent delivery service in East London, and was told that the driver said the Education Dept was closed and they could not deliver. Nobody had phoned the recipient. I was assured it would go out on the Wed morning, as the driver was already out. I phoned again on the Wed to check that it had in fact gone out, but nobody could find any information re the previous day's discussion/promise. I insisted on speaking to the driver, who was there at that point, and he agreed to phone the recipient and deliver the parcel. The parcel then eventually arrived at the recipient after 8 days, instead of the promised 3 days max.
