Unable to get money out of Stessa cash management

I’m trying to resolve this issue and getting no response from Stessa. My rent has been deposited but I can’t transfer to another account without contacting support. Turns out there is no way to contact support. Multiple emails and phone call and NO RESPONSE. what gives. I’m thinking about moving to another platform. It was really easy to start depositing money. Now getting it out has been a nightmare.
