Back and forth frustration

A package of mine was shipped on the 16th of April 2026 through fedex and paid for a international priority shipping, the package only arrived the package arrived on the 3rd in SA, i then received a delivery exception stating fedex can't deliver due to not being able to collect payment but i didn't receive any communication from them attempting to collect. I then contacted them myself to make the payment and also app**** for my delivery address to be amended as my initial address was in a remote area and i thought this would expedite the process of me getting my package. The package was due for delivery yesterday 06/05/2026 but FedEx still handed my package over to their service provider that services my other adress which now further delayed my delivery. I phoned fedex and spoke to Siya and i said i want to rather come collect my package in person and awaited his feedback, i subsequently pboned back again and heard that the service provider would only give the package back today and i would get my package tomorrow this is really frustrating, i had to use that package yesterday, I'm not happy with fedex service.
