If maintenance is going on for almost a year with the exchange team showing no signs of solving the situation, that's pretty much hostaging funds.
Latest announcement from them about ARRR is the suspension of withdrawals and deposits which was 9 months ago!
Due to Node Maintenance,CITEX suspended the deposit and withdrawal services for ARRR. Time for resumtion will be announced separately.
and ARRR team has expressed their lack of cooperation
The CITEX team initially showed some interest in fixing the ARRR wallet. However, as of late they have been unresponsive to our messages. The last reply from them indicated that their technical team has sorted everything out regarding the wallet and is awaiting other departments before enabling deposits/withdrawals again. The ARRR team will continue to reach out to them.
Made a throw away account and more than half has their withdrawals closed, check here

I'd stay away from them : ) Best option imo is to get your funds out of there fast, convert it to other cryptocoin which withdrawal is available as said by other users.
