Hello sir,
I joined wooe.in test series and brought the test series for gate cse and i referred my friends and as per your offer you should pay rs 20 /- per successful referral and i referred 9 friends but did not receive cashback of rs 20 /-. So i request you to please look into this issue.

I even sent mail regarding this but no reply.
