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, I've always had a positive relationship with them and of course you wouldn't expect them or anyone else to make it a practice of replying customer support issues in a public thread.
They're busy with the ShortEx IEO (now in Round 2), but yeah. Telegram's the place for a quick response on customer support. Get on and ask away.
Just sitting on my MBI and waiting for the port =)
