You can merge your accounts anytime, right from your JioSaavn app settings > Edit Profile > add the email ID, mobile number, or Facebook account that you use to log into your other account. This will combine your data and login credentials.
Please note that two accounts with the same type of login ID cannot be merged (e.g., two mobile number accounts).
If you need more help, please write to us from the JioSaavn App Settings using the 'Contact us/Chat with us' option.
