StashFin — Mental harassment

In 2021 I borrow some amount from this app, for some reasons of COVID I was unable to pay EMI on time, after that they call my contacts and destroy my fame and socialism.
They call a senior person too many times and because of this I was kicked out from my JOb .
After that they will continue herrased me on call and msgs.
One day three agents talks to me on a single call and told me that if you pay 5000 amount within 2 hours then your emi will be closed permanently I have paid that amount through a link which was sent by them.
After that they will continue herrased me and not closed my account and increasing EMI amount successively
After that I have sent a email on support and try to call customer care after a long time period of 2 year they will respond I have talk too many agents and told them I have paid a asking amount which was told me on calls I have raised a ticket on customer care but they will not resolve this and again start sending msgs and call to pay
