Bittrexhelp155

I created a post yesterday about an issue I was having with my Bittrex account that is 5 years old, and got a chat message from Bittrexhelp155. They directed me to an a supposed official chat, where they wanted me to download a trust wallet and resync my account.

Does this seem legitimate? In the meantime I also received an email from Bittrex support, letting me know on in the queue for assistance.

The chat I received from Bittrexhelp155 seems like a scam. May I please get your thoughts ? Should I just wait for the official ticket to be resolved?

Thanks
