Sofi restricted account left with 0 money

I received an email at 320am from sofi to tell me my account was restricted and they are conducting a review. There is absolutely 0 reason why this is needed all I do is buy groceries use uber general day to day activities. The restriction left me with no way to get to work as I use uber. I know i should not have all my money in one account and this experience has taught me that but seriously i dont think anyone expects this to happen for 0 reason. My question is how long do these reviews usually take? I have filed complaints with BBB CFPB OCC and FDIC this may seem like a lot but i literally have nothing and dont know what to do.

Does anyone have any idea what to expect next after filing these complaints or any idea of a timeframe
