Jumbo Electronics — Rtx 3080 at 2800 rupee

I got his contact no from quickr.com. As the selling prize was attractive, i contacted him. He told jumbo electronics is giving bonanza offer. He told me to send 4000 as advance and the rest after delivery. So i send it after that he again told me to send 2500 which will be refundable for coureir insurance. Little suspicious with that move from him, i told him to refund my money. After some time he stop replying my msg.
