Waa, more days lapse, still no results... I keep getting the run around, its because of my financial institution... I explained that cannot be possible because

1) I have "other" accounts that renew fine from the same CC
2) I did a guild master realm change last week and was same CC
3) I did a faction change on a different account with same CC worked fine
4) Anything from 2 other wow accounts all under same Bnet will not faction/realm change and error occurs.

So how can it be my financial institution + I tried using my fiances CC and same error happens, contact blizzard.

They told me to try and use some other form of payment lol.... /faint

Im out of idea's and stuck not being able too faction change toons from 2 specific accounts. /cry
