Mobikwik — Money debited but not credited to merchant and no refund to source.

I have made a purchase of Rs. 2234 from the myntra app and paid through the MobiKwik Zip wallet but unfortunately it got failed. But the MobiKwik app is showing transaction successful, it is an pay later payment. Now, when I have raised this issue with merchant and the MobiKwik they are blaming each other but my issue not resolved yet. I have also received the order and paid through the cash and later I returned back one and cancelled the order two pants, because of payment issue. Please resolve this issue as it is showing transaction successful in MobiKwik wallet, which I have pay to the MobiKwik for pay later scheme. Please resolve this issue asap.
