Issues Registering Austrian Phone Number Due to Business Name Mismatch

I am trying to register for an Austrian phone number, with my business that is registered in Austria. All names match incl. the supporting docs, but I still keep getting this error message: The Business Name is missing. Or, it does not match the Business Name you entered within Business information. Please enter in the Business Name shown on the Excerpt from company book or registration or make sure both Business Name fields use the same exact inputs.
