Really bad service received from Fedex. My problem still not sorted out.

I have a contract phone still under warranty coming in for repairs at the Telkom shop. Fedex charged me VAT and import taxes and after informing them that the phone inside the package was sent for repairs and then to be returned to the contract holder, they promised to fix it. It was referred to Palesa Mogadime in Cape Town, Desiree Schroeder at Customer Services as well as Merle Croy Antha, Asha, Boitumelo and Swike. All of them just sending messages to clearance department to fix it. But up to now I am still waiting and they refuse to let you speak to a manager. This is easily the worst service I ever received from any service provider. You cannot complain about the service because there is NO service. Pathetic.
