Postnet are the worst ever

Cannot be more disappointed!!! Paid for an over night delivery, of incredibly important documents, from Ballito to Newcastle, on Thursday, was assured they will be in newcastle on Friday. Now, after calling head offices , I've been told these will only be delivered on Tuesday next week. DISGUSTING! I now need to get more originals of the documents, and drive it up to Newcastle myself, so that they are there ontime Monday morning. Thank you for NOTHING postnet, you have ruined two days of my life, made me pay for it,and put my company at risk with your ******* service.
