Why do I have to contact quickbooks 5 times and they promises me everytime and still nothing done

So there is a chargeback on my account and quickbooks need to verify billing information a credit card.  Contacted the customer and customer cannot verify it.  OK so we have to cancelled customer order.  Done
Thought everything is done but now I have invoice other customer and quickbooks holds those invoices.  I called and they want me to provide the billing address for the other customer.  I told them that original customer is fraudulent and pleaes remove it and release my other funds because it has nothing to do with it.  And yet.  5 times.  5 hours if not more.  Have to repeat myself everything single time and scream at them and still yet nothing done.  Always promise someone will get back and nothing happen.  
I need suggestion how I can complaint or do something about this because they holding my funds almost a month now.  Bassically they took my cash flow.  This is not right
