Hi there! Apologies for the frustrating experience. It is likely your brand failed due to a mismatch in the company information you provided, most likely because of a mismatch between the registered tax ID and the registered business name. The information you enter for your brand registration is verified with third party sources. If it cannot be verified/is not found, then the brand will be in a rejected state.
Please see these articles for more assistance on how to enter the correct info for your brand registration:
