Shocking service from FEDEX

Unbelievable how a company as big as fedex provides such shocking service. I'm awaiting a parcel from USA. A day after it left USA (wasn't yet in SA), a representative called me asking for my email address so that they could send me a invoice. I continued tracking the parcel online and everything was going smoothly but then a day before delivery date, the tracking website shows "hold" due to non payment. I called and turns out the representative had taken my email address down incorrectly. Went through the process of confirming email again using the "alpha, bravo, Charlie, delta" to confirm that it was correct and was told that the invoice would be resent immediately. Well no invoice came Called again and went through that whole process again. Eventually got invoice which I paid immediately and sent pop. Emailed agent to confirm receipt which she confirmed and said she'd arrange delivery. 24hrs later, tracking still shows on hold, delivery pending. Sent same agent who I was dealing with, an email, got automated response saying she's out of office. Called another agent. Said she'd email operations and escalate my query. Not holding out any hope. The parcel I have coming is a machine part for a client. Chose fedex and paid a very high price for shipping (which I don't mind as long as the service is good), but at this rate I may as well have used one of the cheaper couriers where ****py service is to be expected. Won't be using FEDEX again ever. Seems they're going down the same road as a lot of other companies in SA. *********** staff and total lack of service delivery or accountability. So sad
