[Resolved]  Flipkart — I want to change my Flipkart account mobile number without old number OTP

I have created a Flipkart account 6-7 years ago with a mobile number 3-4 years ago I lost my SIM and deactivated of from my side.

The main problem is when I tried to update my new mobile number, the OTPs 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 don't have it. This is making me unable to change the mobile number.
Please do suggest me to update my new mobile number to my Flipkart account. And my old number is issued to someone else and now he is using that account

Thanks
