QBO seems to think I owe them money all my invoices show paid. The invoice they show me doesn't match any invoices I have and they have refunded me twice in the last two weeks two different amount. They have now locked me out of QBO it takes forever to get a Tier 2 support to call you. I can't do my job, my clients are getting mad and the customer support at QBO is terrible. How does a company say that you owe but refund you money, what is going on with the development team in the background that can't fix an issue they created. 
It won't even allow me to change my billing information so I could at least get back to work.
