Hi. I have the same situation now. They locked my account for no reason. They requested documents and I quickly provided them. But they do not check them and for several days they have not responded in tickets.
I looked for some information about this exchange and found that in 2019 they already had a similar situation. When they had difficulties with the availability of funds on their accounts, they did not think of anything better than freezing traders' accounts under the guise of KYC requirements.
