Hello Jill - we are glad @exyle brought this to our attention in our discord- and we have released a full explanation here. We apologize for the inconvenience, our partner Netcoins used Binance for their liquidity but cancelled all connections due to the recent hack, for all coins and not only STEEM. They have now reestablished service using Bittrex.
If you are still waiting to hear back from Netcoins, let us know and we will also contact them about your issue, we will make sure there is a resolution to your experience.
