Razorpay — Supporting fraudulent merchant and not processing refund refund

I did a purchase online at one of sites abuggy.com and i never received any order confirmation nor did i receive the product...after multiple follow ups they said they are processing refund and it has been done till now ..i follwed with razor pay and theyb asked to check with bank...i m following with bank from last 3 months and credit is still not there...
Razor pay has not reverted back to my latest emails also..
The txn is dates 11th July and i have been following with abuggy, razor pay and standard chartered Bank but credit has still not been processed...
Razor pay should give money back as they signed up fraudulent merchant and they acted as intermediary in between bank and merchant..
