Unproffesional Conduct

BradenExpress located in Memphis, USA, was used to send 2 packages of 16 kg's each to South Africa. Since then their telephone numbers do not work. They have no proffesionalism when communicating via email and just keeps asking money for clearance, insurance and delivery. I suspect it to be *****. How do I go about reporting this and getting my money back? Still have not received the packages since 7 October 2023. They say one thing and the next moment there is late payment fees or account number has changed and did not receive all invoices. The tracking of the parcels are only updated untill 21 October 2023 on their website. I really do not think this is legit. The one moment they will pay the outstanding amount. The next I have to pay. All in writing on email. Then they blame myself as a bad customer but their conduct and communication is unproffesional. I just want my money back or my packages deliverd. Even at Capitec the account does not exist anymore. Very suspisious. They claim their systems are down. They even used Sterna World Delivery Services as their new reference. It is miss use of a legit companies name.
