Bajaj Finserv — Fraud company calls

I just went on to check the offers available and i started getting calls back to back and every single person who ever i spoke with did enquiry on my cibil without my concent and people even fooled me from calling or naming different banks now i am scared off my information been shared with everyone and been used in incorrect ways. How could you people even do this.. from afternoon 2 till evening 7 there have been 5 requests placed on my cibil.. just because of your useless service.. and use less customer service... These has been a real night mare...
