In which case I'm afraid you are out of luck. The phrases which you have are simply encodings of the hashes of the passwords you used for the wallets. They are a password recovery tool, nothing more. If you do not have the wallet ID, an email address linked to the wallet, or the aes.json file backed up, then you have no way of accessing your old wallets.

You can try to keep harassing blockchain.com support about it (they are awful and will take weeks to respond), but it is unlikely they will be able to help if you can't provide any more details about the wallets in question.
