I'm 45 min out unfortunately, but what you could do is get a vanilla install of WOTLK going (if you have the CD's) and buy a prepaid Web Africa account for R70 and download all the patches till the latest one from their freezone which won't cost you bandwidth, only a bit of time.
m00t suggestion because you obviously want to start playing ASAP, but still an option if you don't have any luck
I dont even need the latest updated client. Vanilla install of WoW up until WotlK suits me just fine. I can do the patches myself just downloading 18GB on a 384 isn't how I want to spend my weekend
