Bajaj Finance — forfeit commitment

Address:

Mumbai City, Maharashtra, 400706

I have opted for Line of Credit loan which is similar to overdraft from Bajaj and they gave confirmation for the same on email. Now without my notice they have converted it to normal personal loan and started recovering money using my ECS payment from my bank. I have written multiple emails and follow up on phone to Mr. Pradeep Mishra from Bajaj but no update.
My loan account details LAN No:[protected].
This is not acceptable.
