I have been using it for around 6 to 7 months. Initially tracking was super fast. Again it depends on the website some websites like jabong Snapdeal amazon track really fast n offer super cash back offers.however I have not my cash back tracked many times esp from foodpanda etc.
So its always worth a try as u r never gonna lose anything. If ur cash back doesnt get tracked its worth it to send a mail to their customer care they r really quick but sometimes some cash back gets canceled too.like my zovi cash back got canceled.
They take around 2 months to confirm your cash back. Once its confirmed u get the refund to your bank account within a day sometimes n sometimes its taken as long as a week too. You need to have minimum Rs 250 confirmed cash back to redeem. Its really an amazing experience. So far got around Rs 1500 cash back.really happy with Cashkaro.
