poor communication

I made an overnight delivery with Globeflight through Rush on Friday, which couldn't be delivered on Saturday because they do not work on weekends. Great, Now it's Monday, my Sister in Witbank, Didn't go to work so she can receive the order, only for her to call them in the morning saying she hasn't received her parcel. She calls me and I immediately call Globe flight and they say the driver is on the way, mind you that was 10 in the morning, we waited for at least 4 hours to find out what was happening since the Globeflight parcel tracker says nothing about the Parcel except for that it was picked up on Friday at 12. My sister then calls them again to find out and the Lady at Globe flight, who was rude says the package has not not left the hub. Now we are confused so she calls Rush again at 14:00 and they say they will make the delivery today , Rush even sent an email between them and GlobeFlight confirming that the Order is out for delivery. Now it's 18:00 in the evening and still nothing. An Overnight should have been delivered today, Witbank is only 1 hour 30 minutes away from Johannesburg. I've spent so much airtime on this issue today, at least if we were getting updates from the courier company but nothing from both companies. I'm more irritated with the inconsistency and the poor communication from Globeflight. Both Companies need to ensure that the Parcel is received by Tomorrow.
