it have been 5 days until now, nothing at all. No reply, no advide, nothing from mod or admin of bitvest! Who can trust them?
Have you read at least some of the comments?
After all, everyone clearly wrote to you that Lightlord (owner of Bitvest) has health problems and has been inactive for a long time.
You made a mistake yourself, so don't blame anyone else, just ask for a refund and wait patiently for a response.
