Mobikwik — false promises by mobikwik

Address:

Mumbai City, Maharashtra, 400097

I had done shopping on 29/9/18 from grofers for rs1020 and paid through mobikwik. It was promised to me that i will received the voucher for electricity bill worth rs 500... And will received the same by 04/10/18. I was waiting for the voucher but didn't receive it.
I think mobiqwik is fake as this was my first transaction.
Please do the needful so i trust again on mobiqwik.
Hope u all will reply as soon as possible.

Thanks
Hemali
