[Resolved]  Flipkart — Need to change my number without otp

I have created Flipkart account 1 year back with a mobile number a few months ago I lost my mobile phone and the number.

The main problem is when I tried to update my new mobile number, the otp's are being sent to both the new number and the old number. I got the new number otp and account password, but the otp of the old number cannot be entered as I lost the number and I dont have it. This is making me unable to change the mobile number.
Please do suggest to update my new mobile number to my Flipkart account.

My old phone number is [protected] with which the account is connected. I want to change the number to [protected]. My account email is [protected]@gmail.com
