Hello Friends, I am looking help and valuable advice.

while searching some old cd's i found some text file where i wrote email+password and login info of blockchain.info like Wallet identifier+login password+associated email Id. But now i don't have access to attached email (which i create in 2016-2017). Here one thing i wanted to mentioned that i don't have seed or privatekey and retrieving email access is also not possible simply because i that time i use Tata Docomo and now the company is no longer work in my country. and that mobile number also not in used/issued to anyone (as it said not exists), hence unable to receive code from email service.

My query is How to find privatekey or seed from the info which i have or to access my  blockchain wallet using blockchain.info/com

(1) I try to get wallet.aes.json file using https://blockchain.info/wallet/<insert wallet ID here>?format=json   (by replacing my wallet Identifier)
(2) When i try to drag the wallet.aes.json file to the box in In https://blockchain.info/wallet/import-wallet 
 It prompts you to use password and when i enter password it shows an  error "Unknown Format".

Is there any way to get the PrivateKey or Seed from this wallet.aes.json file which i create through above mentioned method?

I have only:
Blockchain.info login Identifier + Login Password (Don't have seed or memonic )
Associated Email Id + Email- Password (but can't have access to it because it ask to verify through Code by associated Mobile number)

Any help i greatly appreciate.
Thank you
