[Resolved]  Flipkart — Cant change my number

I want to change my number as my old number is no longer active and i have no access to it but flipkart sends otp to both the numbers why would i change my number if i have access to it anyway and also flipkart no longer has customer support email and no customer support chats with you only way to reach them is through the call back they do only on the registered number so basically i cant reach customer support because of their illogical and stupid way to change number. Help me change my number if you cant i will have to deactivate my account.
