You can contact their support regarding that and follow it up in social media accounts. Here are the links:

But if you want to access your funds quickly, I suggest to import in in electrum as blockchain.info's support is a close relative of turtles.
In electrum:
Standard Wallet --> I already have a seed --> Enter your recovery phrase --> Options --> tick the BIP39 Seed Box --> Leave the derivation unchanged --> Set a stong password
*Imported Addresses are not included in your recovery phrase/seed
