Payments and Checking Closed - NO EXPLANATION

I own a marketing company. I’m also a photographer. 
 

I moved my banking to QB to streamline. 
 

Today my account was closed. No warning. Zero explanation. No emails of documents needed. No outreach at all whatsoever. 
 

theres $633 in the account. 
 

I call the emailed number to reach out to the “team”, they can’t help me - so they transfer me again - they can’t help me and say I need to go to the risk department. I sit on hold for over 2 hours. No answer. Call again - same process - on hold another hour and a half and was hung up on since it’s now 6:45 PST. 
 

green dot will not help me. 
 

quickbooks will not help me. 
 

intuit wont help me. 
 

So what’s next? A lawsuit? There’s many reports of this happening. I can prove my business. It’s in print. 
 

I’ve tried every link - every number - every chat and this seems like fraud.
