I reviewed my college & got a message that Rs. 100 would be credited in my account till 11th May'18 but I haven't got it. What should I do?

Hello, I can understand your query and I would suggest that you wait some more time for this as my friend also didn't get any amount of review task. It will take some more time to credit the amount in your Paytm number if you have given the paytm number to them.
