Was created 3 years ago... Don't see it under settings :S
Your wallet was created 3 years ago? So in the end did you have bitcoins there at the time of the fork? If yes and you still can't see an option for bitcoin cash. Then you should contact their support regarding this [ https://support.blockchain.com/hc/en-us/requests/new ] as they can verify it anyways and as well as you. Just post your address on any BCH block explorer e.g. https://www.blocktrail.com/BCC.
You can also export your private keys on blockchain.info and import it in any BCH client.
Sweet will do. Thanks
