I'm so sorry that happened to you. Yobit is notorious for being a scammy exchange. I really don't know why people still trade on it and I hope more people like you will share their experiences so the community is aware of what Yobit is doing (or in your case, NOT doing).
Thank you also for the reminder to set up 2FA. It's so easy to do but is incredibly important.
No need for being sorry.. if only then for being dumb enough to have a lesson like that.. still bit sad about the exchange part . I mean how is it possible not to understand a real problem situation and have no solution/ don't want to listen when i wrote about it
