Rupeeredee — Rupeeredee harrassment

I had availed a small loan from Rupeeredee thinking it to be RBI approved loan. The petty loan was divided into 3 months emi but on the due date it is asking to pay double the amount Rs 9000 Rupee Redee has knowingly put its app on technical issues and harassments over phone to pay twice the amount or will again double the amount. With lots of harassment I feel like committing suicide. If anything happens to me I wil hold Rupee REDEE responsible
