Welcome to Justanswer.com, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
You can add your green dot card as a bank on the paypal account.
First, you need your routing and account number for the green dot card.
Then on paypal, go to add bank. Add the green dot account and routing numbers ( make sure they are correct )
Then, once your bank is added ( greendot ) you can withdraw 1000$ a month from paypal to greendot. But I strongly suggest when you make a withdrawal, only make one withdrawal at a time for no more then 499.99$ m If you withdraw 500$ or more at once, then many times Green dot or paypal will reject the transfer.
With that being said, I could probably help you figure out and resolve why it is that youre not able to pay your i nvoices with Paypal if you wanted to discuss that issue.
