PhonePe — cashback amount generation system is not proper

Address:

I have many transactions on phonepe and each time the cashback is within range of 5-20 rs max cashback.
3 times i have paid a bill of 2500+ and each the cash back was 5 rs only.
Recently i have paid my last bill and the cashback was 7 rs only.
When i asked about the logs of transaction more than 10000 rs receiving 1000 cashback they refused it to show.
The system of cashback generation here is a fraud and making publicly fraud to people paying in order to receive cashback.
They are just marketing in the name of cashback upto 1000 where in their logs on one had reached that amount.
Want a strict action to be made against them by government of india so that they don't do fraud to other people.
