SBI CREDIT CARD DIVISION - Online sale of Bicycles on Facebook

I paid Rs. ****/- on **/*/**** for the purchase of an electric bicycle in response to an ad which flashed on FACEBOOK. The company specified was fasterindia.myshopify.com They had sent one link for payment and I used SBI Credit Card, which mentioned the recipient as receiving the payment through some razor payment gateway. As confirmation they sent back one link that is not working today. It is this:
https://fasterindia.myshopify.com/***********/orders/*******bfc***fb***c**d***f***e**/authenticate?key=***a****b***e**b*c*****cf*ce*bc*
I want people to be protected from this site and not to get cheated by this company. If in a day, they get **** bookings like mine, They will collect ******* in a day without doing any thing.
I approached SBI Complaint section and they say nothing is possible. Here is their reply
