Flipkart — Airpods 3

I have purchased airpods 3 from Flipkart on 6/5/2022 but the serial number on the box is different from the invoice due to which iam not able to register the product on apple website
I have also logged complaint on Flipkart customer care regarding invoice of my airpod3 my complaint number isIN[protected] and my Order ID - OD[protected] .but in my app it is showing that my case is resolved, but still i havent got my new invoice in which serial number of my product which is W2NPXMKF6F mentioned. So it is my humble request that kindly help me in providing me my fresh soft copy of invoice where serial number is mentioned, so that i can avail service of the product.
