Hi
I have paid to several websites where they had 100% cash back offer if i used mobikwik to pay. The details are below:
1. 17/9/16 - debited rs 137 to swiggy (Cashback not received)
2. 24/1/17 - debited rs 249 to infibeam (100% cashback not received)
3. 29/1/17 - debited rs 1360 to zivame (No cashback)
4. 31/1/17 - debited rs 195 to swiggy (No cashback received)
5. 26/3/17 - debited rs 160 to zomato and got a super cash of 32 in the app but it expires on 15/3/17 (Date shows it has already expired even though i got it yesterday.

I have even raised this complain to them several times but they haven't replied to me at all! Now, even the app doesn't allow me to send them queries as my previous questions to them haven't been resolved. Please help!
