A gardening website offered a 30% cashback to its customers.
The cashback coupon was to be sent on 21 October 2018
However it was not received.
The domain investor had to open a support ticket, and only after a delay of some days, the coupon was received

This clearly shows that the cashback was not automatically provided or was blocked by the shivalli brahmin fraudsters hathwar, kodancha as part of the google, tata job for relative bribery deal
