Im had same problem as u. Do u still have backup of wallet file? They send u this by email when u first sign up. If u have it u can use this file to make new wallet and access ur funds.

https://blockchain.info/wallet/import-walletHi, don't have the backup phrase that's the problem.
Could you try to login again, but this time use a VPN and try again. If this didn't work the only way that I think you can do now is to login your account from time to time until you get response from blockchain.info like potato chips said because I heard someone here that they solved their issue by logging in from time to time same as what happened to me before and I try to change my IP every time I login.
Once you're lucky to login you should backup your seed by retrieving it into your email for the future recovery.
The other way is to login via VPS, you can use the free from AWS because it's working fine to me when logging in with remote desktop in AWS.
Hope this help.
