Bajaj Finserv — Emi recovery agents call harassments

I Had purchase a washing in finance of Bajaj Fiserv . I had made payment of 2Emi's all were done on time. my salary wasn't credited on 3rd month just one day passed after my due date which i couldn't pay then. constant payment follow calls came from there team every 30 mins, despite of explaining my scenario even after saying i will pay in the next month, along with late payment fee charges. they were constantly calling up and giving mental torcher, on the 10th day of the person from there team saying branch manager call i told him the same, he said give us the product back we you can pay all the dues and then use the product. i requested him again saying i will pay in next he still continued the same, saying will send his agents pay the dues. I informed him i will return back the product pay me the amount which i have paid so far. he started if you want go to court and take. will issue court notice. I Humbly request Indian goverment authoraties to look into it. just becuase of 10 days of late payment there representative agents can't treat us in this manner in the name of recovery.
