lost nearly 3500 rupees.

I ordered 2 kurtis from sweta of Anvi dress hub. They asked to pay 50% advance unpaid 25o. They messaged saying the system not accepting and asked to pay according to invoice which was 289.95. I paid 290 they said system not accepting. I asked refund. they said they can cancel only if I pay full amount. they even shared aadhar card copy but it was scam. like the same way I lost 900 to saba khatoon of collection manaa. but that was a scam page. registered complaint but no response. decided to buy only from known circle or shop physically
