I have created my Jio account using my number. Then i started logging in using my original email added while creating the account. Now I have changed my email. That seems to have created a new account. Because now I am unable to change the email back to original one as it says original email is already in use. I am able to login to the same account using the number, original email ID, as well as the new ID. Please help me merge all these accounts into the one with my original email, completely unlinking the new email ID.
