Get your taxes done using TurboTax

I am sorry that you have had so much difficulty.  

Intuit has a centralized billing department and that computer has put a hold on your credit with Intuit.  I do not know why that happened but know what steps you would need to take to have that hold removed.   The billing department is located in the Mountain Timezone.  It is only open Mon-Fri from 9:00 AM - 4:00 PM Mountain Time.   You would have to call on one of those days and during that time span.

The agent who answers your call will almost certainly not know how to contact them and try to resolve your issue another way.  Nothing else will work.  

Tell them you insist on having the billing department contacted and request a manager callback.    This is so rare that the manager will probably not know what to do either but insist that they contact the billing department and resolve the issue.   Once they get to the right department, it can be resolved in about a minute.  But it is a relatively rare happening and not included in agent training.
