Flipkart — Billing Address Change Not Reflected in Invoice

Hi,

I made on order for Apple Airpods on 17/10/2020 on Flipkart website with order number - OD[protected].
While placing this order I was not asked the billing address and by default, my shipping address was used as the billing address. This in itself is a big issue. But then from the cancel order page, I was given an option to change the address which got changed successfully. But now when I received the invoice, the billing address is still the old one. This seems to be a bug with the system. I either need this invoice updated with new billing address or return the order. Not an expected service from Flipkart.

Thanks
