I need to withdraw PHON coins, but the wallet is in maintenance. Can they report when they will solve the problem?

Regards

This mostly happens to some coins and they don't have a feature to let you know if the coin wallet is online or maintenance.

You can report this issue to https://coinexchangeio.freshdesk.com/support/login

For the alternative, if you can't wait you can try to exchange the coin to other coins like bitcoin or eth which is online and then you can withdraw them without maintenance error.
