[Resolved]  Kissht — collection calls

Who authorised the organisation to call the family and relatives if 1 installment is not paid on time?
I think kissht want hard time from customers in order to understand the privacy. I missed the payment for 05/11/2019 and told the lady that i will make the payment by tuesday evening she tried calling my wife and relatives too. I never disclose the numbers to them they are taking our personal information which is illegal i will take up with rbi, social media and court.
