Authorization code for transfer is invalid

Authorization Code Incorrect for a transfer from GoDaddy

What do you do when the EPP Code/ Authorization code in GoDaddy is incorrect.

We have been trying to transfer a domain away from GoDaddy but the gaining registrar's support team have confirmed that the EPP supplied by GoDaddy is incorrect and not what Afilias has in their systems.

There is nowhere to reset the EPP.

Do I need to lodge a formal complaint to Afilias?
