RegisterKaro i e Safe Ledger Private Limited - Refund from Registerkaro

Applied for company registration with Registerkaro.com online and their executives called me and asked for the payment to start the process. As soon as I paid, another person called me and asked me to pay more for another service to be added i.e startupIndia registration. As soon as I paid for this again another person called me for compliance. Means everytime when I pay to them they ask for another payment without starting working on my first request. And the way they talk, it was similar like online frauds you might have seen related videos. After that I asked them please do not process my case and refund my money of RS ***** which I have paid. I have raised so many emails to their employees who have called me ,their support team, their Grievance team. I am doing the followup since *th Feb **** but still no Refund and person are not responding to my calls and what's app messages. Last week one person named Hammer called me and asked for **-** hours to refund and after that he is not picking my calls.
I am really frustrated with the start of this fraud with me in the beginning of my new journey starts.
