Just bumped into this thread and saw last reply : as my experience with bitcoinrush has always been positive decided to direct message on telegram to admins/moderators and am sure someone wil chim in soon.
They recently moved from slack to telegram @MonsterByteTelegram and for what I can understand they are really busy with new stuff.
Yeah, it has been a while since carton said anything, I assume his problem must have been resolved. We all hope of course it doesn't take this long if we ever have a problem but it looks like there was a problem with the support system and not the website itself, these kinds of things happen on online world time to time, even the biggest websites crash sometimes, hell I remember a time couple months ago or so when whatsapp crashed and nobody could talk (same happened with instagram as well, must be facebook servers) so when you are dealing with these kinds of online tech related stuff you gotta just brace for time to time problems.
As long as its not a constant all the time thing we should be fine, bitcoinrush literally has the best odds out of anyone so they are still doing something great.
