for more than a month now i had late delivery's with my packages

As per the tracking website and required actions, i needed to provide an commercial invoice and ID nr, in which i made sure i did via email to fedex. My Package was due for delivery 3 weeks ago,I have send numerous emails direct to to their customer relations( Jezelle Pieterse) who was unable to resolve the matter and she just past me on in some emails to other work colleagues which was not fruitfull at the end, oh and dont even try and send them an email just after 4pm as they finish at 5pm.I have also spoken to Alta Brandt who was very helpful and resourceful to a certain extend as she also mailed me and sad ''she has no idea why no-one have made and attempt to contact me and to why the package is delayed, as i have provided her of what was needed from me. it is really bad service from fedex to make the customer contact them when a package is delayed. I have been using your service alot this year, but i am slowly making my way DHL to have my packages from the US a bit more expensive but worth every cent. each time when I call and speak to someone new, they just want you to give your information and slove it with a group email which bear no fruit to my case at all. there were one instance where i have asked to speak to Jezelle Pieterse and i got told she was on leave and the lady i spoke to stood in for her and it was mentioned to me that she is sitting at Jezelle's desk and PC and that shehave access to Jezzelle's PC as she has her password, where is the profesionalism in that work place, that alone raises an eyebrow. And feel free to pull this call on this particular matter, as all calls are recorded.

For the past month I have been experiencing delays with many my parcels and in some cases where the value of my item is under ZAR500 the people at fedex still go on and find a way of milking money out me on customs behalf, where i needed to make payment to receive my item and at the end I end up paying nearly 100% to the value of my item. In fact they themselves are carrying out inspections and whatever, but you keep on hearing the parcel is at customs just to put some fear into you. I have paid good shipping fees and you cant deliver, what happens now as you have got your money already.
