Mobikwik — No cash back even after offer. No refund when transaction fails.

I am facing serious problems with mobikwik.
In 2 purchase from firstcry i didn't got cashback.
In making recharge to jio my wallet balance of around rs. 5 was used and rest rs. 94/- was deducted from account. Transaction failed, i got no refund.
In another purchase from firstcry i should have got cashback of 10% or rs. 100. I got nothing.
There have been several cases and continous problems, but i cannot even raise complaint as 2 earlier complaints are pending since long time.
I am left with no option but to take legal action against mobikwik. And sue mobikwik in hon'ble district forum.
Regular cheating, fraud and mischief. Where i cannot even raise issue.
