I saw there advt over different places like toll plaza restaurant TV adds & frocery stores.
So when I was booking a ticket for Pan Card club then while in a booking process I saw that they ate giving 300 cashback on purchase of 3000₹ so I opted for this one & paid through mobiwick by registering over the app then once I tried to do payment via mobiwick then I came to know that these are not a direct cash plus you can use only 10% of supercash in single transaction.
they are online thiefs
