[Resolved]  Flipkart — serial number mismatch in invoice

I'm writing this post to highlight the issue that i have purchased macbook air on 21st jan 2019 and received laptop by next day. I have noticed that serial no. Which was mentioned in the invoice mismatched with laptop serial number. I have reported this issue to customer care and they replaced my laptop. This time they have mentioned barcode instead of serial no.in the invoice and i have highlighted this issue dozen of the times to the flipkart customer care and everytime they closed my request without giving any resolution to my issue and this is really frustrating. I felt depressed and cheated by flipkart.
