So it is the password for your GW account?
If you have been away from your account for a very long time there might be other issues, that can slow it down (have heard of people coming back after a long time and their account have been hacked) But dunno if that would slow it down.
Of.c. it could be they are busy atm, lots of other people contacting support?
Either way... don't really know of any ways you can speed it up, they respond as soon as they can usually. It sucks but I think you gotta be patient.
