Website:

I have ordered redmi 3s prime on 05th may 2017 and paid rs.8499/- via paytm. My order id was 102994 but the site has mailed me on 12th may 2017 that they were unable to dispatched the order and my order was cancelled so they were refund my money within a week. But till today i have not received my money back. Ihave send frequent mails to the site but there was no response. The site has blocked my mail id and they were not send me the forgot password link as wel so the site is none other than a fraud. Ensure to refund earliest.
