Robinhood sold off my ETH without consent or an order – what do I do?

I woke up this morning to find out Robinhood had sold off $1000 of my ETH without me placing an automated order or anything. It’s only a grand, but still that shattered any trust I had left.

What should I do? Obviously move away from Robinhood. I also sent their support team an email. What else can I do?

Edit: funding was fine, there were a few $1k just chillin there
