Quikr - Refund not provided

Quikr promised for RTO service (HP removal) and requested for transfer of **** rupees to a link provided by the said Mr.Puviyarasan.
After making the payment there has been confirmation that the payment was received from Mr.Puviyarasan but no invoice was sent except for a reference number.
Along with the confirmation email of the payment Mr.Puviyarasan sent two other email contacts stating as point of contacts in case of escalation.
Renuka.prasad and RTO @quikr.co.in, none of whom have responded to any emails so far.

The payment was made on Oct ** **** and after realising that the Quikr online review was pathetic online with customers being cheated, with RC cards being withholder. In some cases customers mentioned the same names as in this email.
Also the promised service was door pick and delivery which on request for service cancellation, I was asked to courier my card and details to their address claiming some accident to the person who was supposed to pick up my details.

Either ways I requested for cancellation and a so called Namitha.cr@quikr.co.in agreed to refund the amount after cancellation charges of *** or **% are levied on **th of Oct ****.
I have agreed to the same provided that Quikr provides a valid receipt for the cancellation charges.
The Quikr team has not been able to provide a receipt for the cancellation nor were they able to transfer the remaining amount to my account number.
Ramita promised to send updates by **th Nov ****, but there has been updates from their side.
I have cautioned them that I would be approaching Consumer Court for failed service. Please refer to my attached email for the same mentioned in bold red.
