I can not play WOTLK because I can not download a Patch when I try to enter the

Hi, my name is ZedExalord. I started about 2 days ago on the server and I'm from Argentina in South America, I was waiting 2 days to download the game and now that I try to enter the game when I log in, it says the following:
Downloading Patch 0%
He stays 5 minutes like this for later
tell me PATCH REQUIERED press the start button below to exit world of warcraft and download the patch.
But I do not know where to download this patch, the download does not start automatically, when you leave and restart the patch does not download and tells me to contact the support or download the game again And I do not expect to wait for 2 days without doing anything waiting to download (I have 3.5 megabytes of internet).
I hope someone can help me.
A greeting.
