[Resolved] Flipkart — not able to update email account

I am not able to update my email account in my flipkart profile. The previous email adress which is registered is wrong and i have no access to it.
While updating the email account it requires otp from new email and otp from old email account and the password but as i have no excess to my old email i account i cannot enter otp.
I have been trying from a no. Of days and i have contaced customer care also but they knew nothing about this... They dont even knew that it ask otps and passwords...
