Ok...

finally i talked whit ROBERT on the Live Chat... but he can't solve the problem 'cause "there are no account with my mail registered".

WHAT???
I'm an old member SINCE JANUARY 2015 !!!!! and problably when i registered wasn't necessary an email...

...but... they know my email because last month 26.01.2018 they send me an email to exchange my cryptocoin before 02.02.2018.

On 06.12.2017 they send me a mail to confirm a withdrawal.

I don't know why they answered me that they don't have an account registered with my mail.
But i hope they solve the trouble quickly.
