[Resolved]  Flipkart — Tp link router

I had purchased a TP LINK ROUTER from flipkart on July 5th 2021. However the invoice that i received is without a sign and stamp nor does it have a print on the invoice stating ITS A SYSTEM GENERATED BILL AND DOES NOT NEED AUTHORISED SIGNATURE. However i have spoken to atleast 10 to 15 representative everyone says it will be sent and wants me to update the email . I do have the recording of all your representative i spoke with and none were able to help. They place me on hold and line disconnects. If this is really a forum for solving an issue . Request you to help me with a valid bill.
