Flipkart — Not providing invoice of the product I purchased

I am unable to download the invoice for the product 'Realme buds air 2' from Flipkart app. Hence raised an issue on[protected] and till date they haven't resolved the issue and provided me the invoice.

The product is not working now and require that invoice for claiming warranty. But even after 22 days of raising issue and contacting their customer care multiple times, they are not providing the invoice.

Please do the needful
