Quikr — fake seller listed on quikr - mobile advt regarding apple iphone 7 plus

I had a conversation with seller listed on quikr regarding purchase of a used iphone 7 plus -128 gb, his advt. Was listed & i sent an offer of rs.31000, he accepted & shared his number. I had a conversation with him & he said to transfer rs 3000 via paytm for confirmation & rest afterwards, he shared mobile pics, imei number & even a parcel pic from dtc that it is ready to be shipped as he is in urgent need of money. After it he blocked me on whatsapp, neither responding on call, nor picking up the call & even deleted the advt. From quikr.
His no. [protected] & he told his name as raghav/ sameer.
(Pics attached for reference). Plz help me in getting back my amount sir & prevent people from such people duping honest public.
