I sent ENT coin to Yobit but Yobit's ENT wallet is still in maintenance. when I request help from yobit's helpdesk, below is their answer:

"Deposit\Withdrawal coin will be available after you upgrade the source code of the wallet. Unfortunately the developers are in no hurry to send you updates.
- therefore, in order to avoid the loss of users, the network is not available.
If you have updated the source code of the coin, send us (https://yobit.net/en/maintenance_request/ Free)and we will promptly correct the problem on the coin."

I sent my coins about 1 month ago and I am still waiting.

can anybody help me? Is there any dev who can help me?

thanks,
