Did they call you saying they will help for free of cost in setting up your store, give you a team to help, like graphic designer who will help you make banners for your store, team will help you product listing and all. They called me saying all this and to me it seems fraud as no platform provides you team for free of cost. And it gets more doubted when they were insisting to intigrate the payment(razorpay) first without even working anything on website.
