Zeb pay - Refund from Zeb pay

I have been told by the company on telegram that if I invest a certain amount and then after completing the order mentioned I will get my full refund with the bonus of **%.
But the order amount was not mentioned earlier only the *st order amount was mentioned by them. Yesterday on Jun *, ****, as per the instructions received I have done the transaction of ***** rs (transaction upi id - ************) to the upi id - kum******@airtel After the transaction, they have again given me the *nd order of ***** rs and they said after completing the same I will get the full refund if I don't do it then they will not return my serious ***** rs.
So again I sent ***** rs (transaction upi id - ************) to the upi id - kum******@airtel and after this again they are asking for * lakh rupees from me as a *rd order. And when I said I have no funds left in my account then they said they will not refund the amount that I have paid unless I pay * lahks.

So I asked them and requested *** times to please understand the situation I was not aware that they will ask for this much money otherwise I would not have sent them the amount. So I asked them to at least refund me my ***** rs but they denied it and said they will not refund the amount.

I would request and beg the authority to please see to my concern and refund my amount as I have nothing left with me. I also have the transactions screen shot with me.
