The undeliverables

Waybill *** is stuck in SA on route to Botswana. It's been stuck for more than 10 days even after I emailed the customs invoice to the incapables in Botswana. Never heard a word back, included my phone number in the email. You can't call them either in Gaborone as they seldom/never bother to answer the phone, even when they do, they're incapable. Previous incidents include unilateral changing waybill numbers, so that a package is untraceable. My personal list of mishaps with Fedex are numerous. I would advise anyone against using them but unfortunate I had no choice on this waybill, their poor service was selected by the sender.
