Usually it taked around 24 hours, but it might take longer in some cases As account related issues aren't handled on the forums, just wait until they reply And uhh, have you checked the spam/junk folder?
I think that they have quite a much work to do, so depending on the issue you have, it can take them more time to look into the things and analyze them properly. Let's hope that they will answer your call soon. Thus, if it's nothing very urgent, I would advise to give them few days for an answer, before trying to address the issue again. Maybe they are already thinking about how to reply
