Mr. Vinod sharma and neha from rbl bank are harassing my friends and family members and telling them to pay money or else they will keep calling them and also threatening me to pay the amount. I asked them if i am talking to them they have no such rights to call any of my family members or friends but they are raising their voices on the phone and saying either pay the money or will tell collection department to call multiple time to my relatives.
I am asking them to give me a written email about the total outstanding amount that should not be more than rs84000 and that i will pay the amountand they will minus the amount from the principle amount i. E rs84000. They are not ready to send me any email for the same. I asked them not to call my friends and family members as i am talking to them but they are saying we will keep calling your family members. I want them to stop calling my friends and family members. I have call recordings that i can share.
