Worst app by google. Review on Google Opinion Rewards

I tried this app 3 months ago. This was the app released by Google company. The concept of this app was that it would provide service for its users and when the users completed the service they would get paid for it. This money could be used for buying Google gift cards . So I downloaded this app and registered my Google account with this app. I got only a single survey which was my profile survey and I got paid rupees 10. That's all that was the last Friday which I have received from 3 months until now. I did not receive even a single survey until now and I was not able to earn any money from this. Everyday I check for new service but I can find nothing. Why do they have to give fake promises if they can't abide by it. What I felt was they are cheating. Because a person who had invited me to join this app was getting service regularly where as I was not even getting a single one. He has earn more than rupees 200. Where as I was not able to earn even 20 rupees. I ask many of my friends if there were getting surveys too but even my friends were not getting surveys. If the Google wanted to give surveys only for selected people then they had to mail it to selected people. They are just wasting everyone's time by creating an app which doesn't even work. Well this happens stop working from months. So this was my experience with this app and I'm happy to share it with you.
