loan recovery agent

i am from Tamilnadu, but some hindi recovery agent tried to call. I didn't accept the call reason, iam in work where they don't allow the cell phone in my work place. then they all chat with an message app so many of them says if you pay the due amount police will reach in your house and the total due amount. other wise we will call you families and friends in bad words. so be careful from fatak pay app. please don't accept the loan offer. it will give mental health issues. this month my due date is 3rd oct, but call me at the same day in evening time because auto doesn't work in my app. this loan provide 42% to 60 interest rate.
