Hello, 

1. ??????? ??? ??????? ??????? ??? ??????? ??? ???????? ??????? ?? ? ????? ????? ??????? ?? ????? ?????? ??? ??? ????????? ????? ???????? ???? ?? ??????. 
2. ??????? ?? ??? ???? ???? ???????? ?? ??? ???????? ??? ??? ??? ??????? ?????????? ??????ation about the vendor. You can file a complaint with the cyber cell who has the authority to extract information as required from anybody. 

- It is well settled law that any service provider like the training institutes, educational institutes/schools or College /university cannot be allowed to forfeit the fees or consideration received in advance in case the student has not availed the service. 

- Further, the clause that the Course/Registration fee once paid is not refundable is unconscionable and unfair trade practice as well as voidable and therefore not acceptable.

- Hence, the said merchant is bound to refund your deposited full amount if you have not availed his services. 

- Further, the denial of refund of deposited amount is also against the public policy and hit by the provisions of Indian Contract Act,

- You should issue a demand notice, and on refusal the same file a complaint for the deficiency in service under the Consumer Protection Act. 

- Since, you have not the address of opposite party , then you can send the notice through online mode i.e. email ,watsup etc. 

- Further , the said gateway is not bond to provide you the address legally. 

- I have done many such cases , where the College /Institute /service provider has refund the amount .

Payment gateway will not help.

You can file a police complaint and a also file a consumer case 

File FIR OF cheating. Payment gateway is liable to provide information about merchant.

Or first inquire from payment gateway and if information not provided, than file FIR.

The ascertainment of the address is the prerogative and the function of the court and police officials. But, firstly, a legal notice stating all the grievance and the addressing the legal notice to the merchant and the payment gateway will suffice your requirement. Provide them 10 days time to refund your payment along with the legal and compensation. The police complaint will be initiated after that in which they cant hide and will be arrested.
