Bajaj Finance — Extended warranty without my knowledge

Address:

Bangalore, Karnataka, 560068

Hey i would like to bring into your notice that i've been charged rs.295/- every month for one of my loans. Extended warranty cd 404ewc14786726.
My id is 20936229. I was not informed about this charge and would never have opted for it and i've been paying for it along with the emi.
I would no more like to pay for it and i want a refund of the money which i have already paid for the extended warranty. Please do the needed.

Thank you.
