Bajaj Finserv — loan emails

Address: 560075

Why are you sending bulk spam emails from a different email address, I have requested many times for not sending me emails on official email id but still from multiple addresses I am getting emails for Bajaj Finserve loan.
I don't need any loan and even in future also if I need I will never take from Bajaj.
If you guys don't stop sending these emails, I will put a case against your firm.
