Rupeeredee — Continuous calls and harrassment

I have taken a loan and paid back to them however they never updated it on their application and then I sent an email to them with the UTR number which shows confirmed. Everyday they are contacting me from 9am and irritating me. 200 calls each day. Please take action against them as soon as possible. Anyway too much interest against RBI protocol also they hack phone's data and blackmail customer
