This may take a while… there seems to be a Blizzard team that scanns Tech Support for issues that cannot be resolved through troubleshooting… such as yours. They seem to be able to pass it on to other staff where it gets “handled” if possible.
In the meantime… take a look at this topic and try logging on on SA or Australia as I suggested. It may or may not work… but it will give you something to try.
