Fedex south Africa...hateful experience

Hateful experience... shipment arrived in south africa pretoria...payed the duties and had the bank generate and send proof directly to FedEx .... 3 days and 7 calls later and I am no closer to getting my package....apparently FedEx is unable to locate my payment...every call I make they instruct me to resend the proof...after explaining that I dont have it the call gets ended after a promise to sort it out with their accounts department...neither that or the promised call back ever materialize...asking to speak to a manager or the accounts department directly only leads to frustration and you left with the feeling that the whole thing is a bait and switch...that in the end the responsibility falls on you to help them locate the money that is already in their account...surely they can locate one payment without me holding their hands....it been three days already...and still they expect me to help find the money.... having finally gotten upset enough to become rude and crude on the phone I got the name of a manager and the assurance that mr St__n will call me back....been more than an hour and still waiting... what upsets me most is that dealing with a big professional outfit like FedEx I initially thought that I messed up a reference no or something and that I will have to sort it out with their admin department or something...but no you will not be able to even speak to someone from that department...all and all...I will avoid doing business with them in future
