[Resolved]  Flipkart — Flipkart mobile number change without otp from old phone number

I have created flipkart account 10 years back with my email address, few years ago I lost my mobile number. Then I decided to update my account with new mobile 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. Thus I am not able to update my mobile phone number which is very disappointing. When I try to contact flipkart customer service they will only call back to my inactive number and don't have an option to enter new number. There is no customer service email address within flipkart to address this concern.
Please do suggest me to update my new mobile number to my flipkart account.
