It's almost a week since I can not log in to my yobit account because I do not receive their authentication code.
What is the email provider you are using? because if it is hotmail or yahoo then this was already expected, these two email providers have had this kind of problem, now if it is gmail and you have not received authentication code, then it must be yobit's problem.
I wrote 4 emails but alas no response from them.
it may take up to a year for them to respond
Of course on my account there is a large amount of dogecoin and also waves, verge etc....
This was a very big mistake that you made, there are reliable exchanges like binance. Yobit are scammers who have had accusations pending for years and see that even years pass they do not change their behavior
I do not know what to do but this lack of professionalism and interest for these clients disappoint me enormously.
hire a lawyer and report your case to the police. This is all you can do.
