Issues like this take time to be resolved since the support has asked you to provide the screenshot of the error login page and you did the best thing to do right now is to be patient to see what the outcome of the investigation will be before you know the next step to take.
1xbit has very busy but dedicated support they will look into your case soon.
You are still defending this website by destroying the reputation of your account. You will continue to lose your reputation, losing 1xbit. Nothing better can be expected from a user who joins the website's signature campaign after seeing so many bad reports.
The support team of 1xbit will definitely reply but it is not to return the account of that user, but to block that account with an excuse. So without defending them, try to earn in a good way.
