Cashe — NOC is not issued

Hi
I had received call on 21st Dec 2020 from one of the executive priya, I asked for settlement, They said that they will waive off the penalty amount if i pay the outstanding principal amount, as of that day, outstanding principal amount was Rs.61403, then after,
I agreed for part payments, they sent the razorpay links and paid the said amount. I believed them and paid the amount.
They said that they will issue the closure letter after receiving the payment.
Before making the payments, I asked for the mail confirmation of the final settlement amount also, they denied sending the mail, they promised me to issue the NOC from cashe.
I have sent email to support email address with proofs however it is now more than 15days and asking to wait. Could you please investigated this and help me get No dues.
I am really tired of following up with executives. kindly do the needful. CLN nor:103326; Loan ID : 531972
