FEDEX express - utterly poor service. Will NOT recommend using this company.

I wish there was a negative star rating option for FEDEX. I am utterly disappointed and disgusted with the poor service(?) from this company. I sent a package to my son in China on 09/10/2023 paying thousands of rands to get it there. The items in the package are mostly SA food brands, education certificates, and sentimental items like a watch we bought him years ago and pictures. The documents in the package are crucial for their employment and is impacting them negatively by being withheld. It was a smooth process up till payment and picking up the package - which arrived in China about 3 days later. But since then its been a nightmare with constant back and forth with their clearance agent that side. Literally 56 mails later, photos, links to products, and our package is still in holding. We've had to declare prices for the same items numerous times, fill in the same information countless times - I even had to specify down to single ingredients in a mixed spice!!! They want me to declare the items especially the watch at current market prices - for a used item, its ridiculous. I understand protocol, as I work in compliance myself, but dealing with this agent is a nightmare. I've escalated this with the MEiSA branch in South Africa, received a complaint reference number and then crickets after that; other than a reply mail asking their agent that side "if she needs assistance???" We the clients need the help!!! I would NEVER recommend FEDEX to anyone and I will discourage anyone from using this pathetic excuse for a service-related organization. They have a huge mountain to climb regarding customer satisfaction. Utterly useless agents - both here and in China office.
