StashFin — Payment not updated, cheated and lied to make the payment

I took a loan from stashfin of 7000/-rs in mid 2021, my loan repayment got delayed due to Covid, I got a message from one of the executives on 18th September, 2021 to make the payment of base amount 7625/-rs and rest of the interest charges would be waived off If I made the payment on the same day so I made the payment of 7625/-rs on the same day, the executive also mentioned that once I make the payment he would close my loan and will send me the NOC but neither he updated my payment nor provided me the NOC. I got another call from one of the executives again to pay 1000/- rs if I wanted my loan to be closed so I made the payment on the same day (30th September, 2021) again no Nov was provided, I got another call on 5th August, 2021 to make a payment of 1000/- rs to get the loan closed. So I made the payment. Now the problem is my 7625/-rs payment has not been updated till now and they are asking me to pay 27, 748/- rs to close the loan. I have made a total payment of 9625/- which is not reflecting on the app. I am getting threatening messages from stashfin. When I try raising the ticket are not letting me raise the ticket nor anyone is chatting with me to resolve this and I requested for the callback which I have not received till now. I urge you to please look into the matter. Kindly resolve this for me as soon as possible. I really appreciate your help.
