Unicornstore.in / Unicorn Infosolutions — Made online pre-booking for iphone13 at Pacific mall Subhash nagar and not receiving payment receipt and booking details

Team, i made online pre booking yesterday for iphone 13 at Pacific mall subhash nagar uni store. Person named prakhar sakhuja contacted me on WhatsApp and asked for payment through QR code scanner and some details like name, email id, contact number, phone color, storage etc. After making the payment he didn't sent me any booking details/payment receipt. Today again if followed up on whatsapp and on call and i was informed details will be send to me today but again no details has been shared with me. Is it a kind of fraud? Sharing chat as a proof as now no one is answering my call. Kindly help
