Cash Sahara is a fraud app

The Cash Sahara app is not giving an NOC after closing. I had a payment due on 17/09/2026 of 4000. On 16/09/2026, when I called, they were abusing me a lot. I paid my payment today itself, on 16/09/2026. I am asking for my NOC but they are not giving it and then saying it's completed. What I want to say is, why aren't they giving the NOC, brother?
